UnicodeEncodeError when deploying Nemo Text Normalization on Triton Inference Server
**Describe the bug**

I have a problem when deloy Text Nemo Text Normarlzation on Triton Inference Server. The Normalizer can not load the default "whitelist.tsv" file. Whenever I run ```tritonserver --model-repository models/```, the bug will appear.

```python
from nemo_text_processing.text_normalization.normalize import Normalizer
normalizer = Normalizer(input_case='cased', lang='en')
```
Results:
```bash
Internal: UnicodeDecodeError: 'ascii' codec can't decode byte 0xce in position 150: ordinal not in range(128)

**Environment overview (please complete the following information)**

 - Environment: Triton Inference Server 21.10
 - Method of NeMo install: pip install nemo_toolkit['all']

**Additional context**

**There is no problem when I test this code without Triton Inference Server!**.
