Multi-language issues

I found some issues related to multi-language.

If login Google Drive account with name using Chinese characters, it will show block characters.

Changing to Japanese language, the wordings for "Drive Backup" will overflow.

So this is because our i18n glyph set is generated from the localized strings present in the project. This is great for unchanging text, but clearly falls apart when there is custom text like names and (in the future) models from the APIs.

We should obviously add in a wider set of common glyphs, but multiple sources online recommend not dumping the entire glyph set for languages as it can massively balloon the size of the texture atlas, causing performance/rendering issues with TMP.
