Current fontset only supports latin characters, so anything outside of what we have in the font file will be ignored and not rendered.

Font is here - https://github.com/appwrite/appwrite/blob/main/app/assets/fonts/inter-v8-latin-regular.woff2

While its likely intended to not support special characters, we will want to do something to accommodate a more standard utf-8 set to allow Hebrew or Cyrilic characters
