Having more characters than possible

I’m editing a font, and I’m trying to fil up all the characters that are missing from a certain unicode range. Now, it says “Thai 1/87”. When I go to Insert characters and mark whole “Thai” range and insert it, it says “Thai 128/87”.

What’s that all about?

The range for Thai contains 128 places for characters, however only 87 are defined in the unicode standard. If you only add the characters that are defined by Unicode, you should end up with 87/87.

More info can be found in the unicode chart for Thai
