how to insert ASCII codes into MYSQL Database
===

i have a this data as a text field in a table.

The quantities displacement (y), velocity (v) and acceleration (?) associated with a body executing SHM are such that

Note : here **'?'** is alpha symbol

now i am generating a .xml file of this data where its inserting **'?'** in the place of alpha symbol like this.


So how i can replace the alpha symbol in place of **'?'**.I have tried with ASCII code ampersand hash 945; for &#945; for alpha but it not working for me.

The reason is i am dynamically generating .xml from the table using a php file.

Any help would be appreciated.Thanks in advance.
