New Thai-Language font is too small with condition.

I don't know if it's correct to post here, it's not really a bug, but more an overlook, but it's a problem for sure.

so lets get started, Thai Font have been changed recently to new font that show all 3 levels of our vowels and consonants but with cost, it is now too small if play with menu language in English, and chat language in Thai(by /global 1 th), it's fine if play with menu language in Thai and chat language in Thai, but I'm having problem with item properties in Thai which is confusing because of our language, so I have to play with menu language in English. I think the old font was fine, I have not heard anyone complained anything about it.
