Python gettext UnicodeDecodeError

Question

I use python gettext module. It is fine when I use language=en_US, but it raises an error when I use another language (e.g:vi_VN). Have I done something wrong?

trans = gettext.translation(domain, os.path.join(os.getcwd(), 'locales'), [language])

The locales folder in my project:

locales/
├── en_US
│   └── LC_MESSAGES
│       └── i38.po
└── vi_VN
    └── LC_MESSAGES
        ├── i38.mo
        └── i38.po

Error

Traceback (most recent call last):
  File "root.py", line 25, in <module>
    trans = gettext.translation(domain, os.path.join(os.getcwd(), 'locales'), [language])
