Installer breaks if username is not in English / With non-english locale?

First of all, I am sorry through the translator because I am Korean.
The current problem is that there is an error during installation through the mode installer.
TypeError: '>=' not supported between instances of 'UnicodeDecodeError' and 'int'
It's an error statement written on the terminal.
- My operating system is [Windows]
- I installed the game [2 weeks ago]
- I am trying the [Full Patch]
- I installed the game [using the Automatic Installer (steam)]
- My computer is a [Gaming desktop]

Sorry for asking Github, not discode, because I am not good at English.
I ran it in Safe Mode, but the error came out the same.
I really want to do it, but I don't know what to do. Please help me.

该错误表明安装脚本中存在 Unicode 处理问题，很可能是在处理非英文用户名或区域设置时发生的。请查看安装程序的主入口点，并追踪文件路径或用户输入被解码的位置。检查字符串比较或编码假设。通过在测试系统上设置非英文用户名或区域设置来重现错误，以找出解码错误的根源。
