This is a list of resources that list web-baed font rendering technologies for various scripts. The idea is that if a person does not have a font that a technique of either font uploading or graphical glyph substitution is used to ensure that a user can still see the text.
Not all of them are useful, most of them probably don’t apply to you as computers can probably render your script correctly. Some are non-Free but may give ideas to people.
Mainly for web based rendering of languages without the need to install fonts. In the worst case scenario it will create images of all the missing glyphs so you can view the webpage without needing to install a font.
