Description
When running the main.py script, a TypeError occurs in the get_language_code method of the TranslationManager class if locale.getlocale() returns (None, None). This happens because the code attempts to check "Chinese" in language_code when language_code is None, which is not iterable.
Steps to reproduce the behavior:
- python main.py
- error info:
Traceback (most recent call last):

Proposed Solution
open translate.py in ./translation, edit line 30 :
def get_language_code() -> str:
# 获取当前系统的语言和区域设置
language_code, __ = getlocale()
if language_code is None:
return "en_US" # Handle None case by returning a default language code
return "zh_CN" if "Chinese" in language_code else "en_US"
