I18n_fastgenerate Failed Reading Unicode File Name

I’m trying to modify translations and need re-compile translations file to implement the update. But when i trying re-compile it with the following command:

$ sudo -H -u edxapp bash
$ source /edx/app/edxapp/edxapp_env
$ cd /edx/app/edxapp/edx-platform
$ paver i18n_fastgenerate

And i found this:

Traceback (most recent call last):

How to re-solve this issue?

Just set LC_ALL to en_US.UTF-8 with command export LC_ALL="en_US.UTF-8" and then trying re-compile it with command paver i18n_fastgenerate.
