Subject: Update: Project f_utf.
X-Git-Tag: 0.5.10~110
X-Git-Url: https://git.kevux.org/?a=commitdiff_plain;h=c3031ed1bdc5b5559642de4cc90d183da959410c;p=fll

Update: Project f_utf.

While investigating the utf8 program, I looked into the f_utf project and found that it is still very much lacking.
At some point in the process of me writing this, the Unicode 14 was released.
I started the process of updating parts of the code and have made it as far as Gujarati with this commit.

Remove unused functions.
Add new functions for detecting if something is a superscript or a subscript.

Update the comments in the private functions to make it explicitly clear when a particular private function expects that only characters of width 2 or greater are provided.

There are some "todo" comments that need to be addressed before the stable release.
I'm expecting another release candidate at this point and so I am pushing off some of the Unicode updates onto after the next release candidate.

I noticed that the unit tests for f_utf only address the structures.
While this is disappointing it does save me the effort of having to write more unit tests for the newly added functions.
