handle non-ascii file names

There are cases when user wants to publish file with different language name. For example, `популяция.csv`. In this case, pipeline fails when adding resource 
```
ERROR :Data Package validation error: Descriptor validation error: 'популяция_csv' does not match '^([-a-z0-9._/])+$' at "name" in descriptor and at "properties/name/pattern" in profile
```
