[bug] Encoding bug in the liscense page of nsis

[Yuxiza]

Describe the bug

I'm in system language Chinese. When adding liscence file to the nsis intaller, I'm having an encoding issue in the liscense page. This looks like an encoding conversion issue between gbk and utf-8. Thank you for your attention.

Reproduction

• Set the system language to Chinese (I have not test English or otherwise yet)
• Add some Utf-8 characters in the license file
• bundle and run

Expected behavior

Display utf-8 characters correctly

使用带bom的utf-8格式就行了.
