This is a part of my code:  $content = ' '; $content .= '&lt;meta http-equiv="content-type" content="text/html;charset=UTF-8"/&gt;&lt;/meta&gt;         &lt;link rel="stylesheet" href="" type="text/css" media="screen" /&gt; &lt;div class="all_block"&gt;';   Don't work UTF-8 but it is set I don't understand where is my problem This is an example of text: 'ja?i ku?ol har? lerp�' Help me please!
I'm setting up a new server and want to support UTF-8 fully in my web application. I have tried this in the past on existing servers and always seem to end up having to fall back to ISO-8859-1.  Where exactly do I need to set the encoding/charsets? I'm aware that I need to configure Apache, MySQL, and PHP to do this — is there some standard checklist I can follow, or perhaps troubleshoot where the mismatches occur?  This is for a new Linux server, running MySQL 5, PHP, 5 and Apache 2.
Multiplying Binomial Terms Two identical files; Apache says one is forbidden Create backup iPhone with forgotten encryption password I'm trying to make a backup from my iPhone, however it's set to be password protected. I do not know the password, as I've never set one. I've tried all the passwords I know, which I've ever used to make sure I didn't set it.  I've also tried the default 0000 and 1234 codes.   I want to uncheck the encryption checkbox in iTunes, but it requires me to type a password. What else can I try?  I have no problems in removing all backups and start from the scratch somehow, however - I do not want to restore my phone as new and remove all those settings. Question on the coefficients of $(1+x+x^2+x^3+x^4)^{496}$ Consider the expansion $$(1+x+x^2+x^3+x^4)^{496} = a_0+a_1x+\cdots+a_{1984}x^{1984}.$$   $\quad$ (a) Determine the greatest common divisor of the coefficients $a_3,a_8,a_{13},\ldots,a_{1983}$.      $\quad$ (b) Prove that $10^{340} &lt; a_{992} &lt; 10^{347}$.   Is there an easier way to solve this and is there a formula for the multisection for just the sum of the coefficients and not including $x^k$?  I thought of using the Multisection formula to prove (a). That is, $$\sum_{k \equiv r \pmod{m}}a_kx^k = \dfrac{1}{m} \sum_{s=0}^{m-1} \epsilon^{-rs} f(\epsilon^s x)$$ where $\epsilon$ is a primitive $m$th root of unity and $\displaystyle f(x) = (1+x+x^2+x^3+x^4)^{496}$.  Thus we have $r = 3, m = 5$ and so \begin{align*}\sum_{k \equiv 3 \pmod{5}}a_kx^k &amp;= \frac{1}{5} \sum_{s=0}^{4} w^{-3s} (1+w^s x+(w^{s}x)^2+(w^{s} x)^3+(w^{s}x)^4)^{496}\\&amp;=\dfrac{1}{5}\sum_{s=0}^4 w^{-3s}\left(\dfrac{(w^s x)^{5}-1}{w^s x-1}\right)^{496}\\&amp;= \dfrac{1}{5}\sum_{s=0}^4 w^{-3s} \left(\dfrac{x^{5}-1}{w^s x-1}\right)^{496}.\end{align*} I would like to use multiple .bib files for my article, such as file1.bib, file2.bib. However, I would like my references not to be separated (such as &quot;Primary sources&quot;, &quot;Secondary sources&quot;, etc.). These bibliographies just need to be merged into one. One way to do this is to copy-paste these .bib files into one .bib file, and this would solve the problem. However, I would like to keep it split into several .bib files, by topic (file1.bib contains articles on topic1, file2.bib contains articles on topic2, and so on). I tried to do \bibliographystyle{alpha}  \bibliography{file1} \bibliography{file2}  but this just gives me the same bibliography twice! Hyperlinks clicked in evince document viewer are not opening, any ideas on how to fix? As it was instructed in another thread here in the forums, I opened the /usr/share/applications/mimeinfo.cache file to check for correct references. And noticed this doesn't seem to be the problem, there even are 3 optional browsers to use.  x-scheme-handler/http=google-chrome.desktop;chromium-browser.desktop;firefox.desktop; x-scheme-handler/https=google-chrome.desktop;chromium-browser.desktop;firefox.desktop;   I already checked that the programs are correctly named, using the "which" command in the terminal, like this:  $ which google-chrome $ /usr/bin/google-chrome   So google-chrome should be the first option and yet the order to open a url doesn't seem to be arriving to the program, not even to the 2nd or 3rd option for that matter anyways.  Also, the 'Get help online...' command in the 'Help' menu doesn't work. So it is not a problem with the specific document file either.  I'm running Ubuntu 12.04 LTS. If you need to ask for more relevant details, please do. It would be nice to have various opinions on how to solve this, thank you :-)  UPDATE: I ran evince from the terminal as asked. This is what I'm getting when trying to open a link:  /opt/google/chrome/google-chrome: line 42: /opt/google/chrome/chrome: Permission denied /opt/google/chrome/google-chrome: line 42: /opt/google/chrome/chrome: Success   Should I try the fix you suggested even if my error log is different?  UPDATE: Tried @maggotbrain's solution and BINGO, now I can study pdf references faster thanks to you bro! What are the subcategories of ordered sets / groups? My son got MineCraft PC for his birthday.  The account is under my e-mail and he has a name in the game (my terminology may be off as i do not play the game).  My other son would also like to play MineCraft, but have his own name (character???).  Can that be done?  It doesn't seem logical that I'd have to download 2 Minecraft games.  Please let me know how this works. C# - Keyword usage virtual+override vs. new What are differences between declaring a method in a base type "virtual" and then overriding it in a child type using the "override" keyword as opposed to simply using the "new" keyword when declaring the matching method in the child type? Why does this not work with an imaginary exponent? Could someone please tell me why this exponentiation rule does not work when the exponent is imaginary?  The following seems to be true but is only true if $x$ is an integer.  $$e^{2\pi ix} = \left( e^{2\pi i} \right)^x = 1^x = 1$$ While I can post external texts into question and answer bodies, it preserves the old font style, spacing and size (although the markdown display won’t be affected by that.)   App Version: 1.6.6.2 Device: iPhone 6 OS Version: Version 11.0.3 (Build 15A432) See all shared items in Google Drive In Dropbox there is a place you can see all the shared items in your account (i.e., all the items you have granted others access to).  Is there a similar feature in Google Drive?  I'm not only trying to find items that are shared with other "named people", but also documents that are shared on a "anyone with link can view / edit" or "public on the internet" basis.   Franck's  seemed to work back in 2013, but Google Drive's interface has changed quite a bit since, and I'm struggling to be able to perform the same task with the new interface. I wonder if anyone knows how to do it in the new interface. Necessary and sufficient condition for the matrix $A = I - 2 x x^t$ to be orthogonal Let $x$ be a non zeo (column) vector in $\mathbb{R}^n$. What is the necessary and sufficient condition for the matrix $A = I-2xx^t$ to be orthogonal? Can I stop 100% Width Text Boxes from extending beyond their containers? Lets say I have a text box that I want to fill a whole line. I would give it a style like this:  input.wide {display:block; width: 100%}   This causes problems because the width is based on the content of the text box. Text boxes have margin, borders, &amp; padding by default, which makes a 100% width text box larger than its container.  For example, here on the right:    Is there any way to make a text box fill the width of its container without expanding beyond it?  Here is some example HTML to show what I mean:  &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml" &gt; &lt;head&gt;     &lt;title&gt;Untitled Page&lt;/title&gt;     &lt;style type="text/css"&gt;         #outer{border: 1px solid #000; width: 320px; margin: 0px;padding:0px}         #inner{margin: 20px; padding: 20px; background: #999;border: 1px solid #000;}         input.wide {display:block; margin: 0px}         input.normal {display:block; float: right}     &lt;/style&gt; &lt;/head&gt; &lt;body&gt;     &lt;div id="outer"&gt;         &lt;div id="inner"&gt;             &lt;input type="text" class="wide" /&gt;             &lt;input type="text" class="normal" /&gt;             &lt;div style="clear:both;"&gt;&lt;/div&gt;         &lt;/div&gt;     &lt;/div&gt; &lt;/body&gt; &lt;/html&gt;   If this is run, you can see by looking at the "normal" text box that the "wide" text box is sticking out beyond the container. The "normal" text box floats to the actual edge of the container. I'm trying to make the "wide" text box fill its container, without expanding beyond edge like the "normal" text box is.
