Agreed. What is in Unicode has already consensus amongst a group of experts. By the way, and to close this off-topic dialogue, is was nice to go through the process at the Unicode Consortium for requestion a code for double barred capital b for https://en.bitcoin.it/wiki/Bitcoin_symbol (the request is still pending at this moment).

We're all mathematicians here, and I've seen strange symbols too, and I think there ought to be a law. Complicated symbols often strike me as a failure in communications skills.

But anyway, the standard is what it is, and the aim of the project is to follow that.

My field is information technology (computer science, electronics and mathematics) and I've seen stranger symbols. ;)

Hi Pander,

I take it that this is a list for which you see special need.

I don't follow how extending these in FreeSans will extend the support for math in FreeSerif.

If you're feeling artistic, please don't hesitate to send me a diff from a recent SVN update. (But write to me for guidelines first.)

I'm not sure I follow your suggestions about scaling. I don't like the sounds of it.

U+219A, U+219B, U+21AE (Arrows)
The intent is to give Sans and Mono a similar subset of most common arrows (NOT to make all the sets the same).

U+2274, U+2275, U+2278, U+2279 (various slashed inequalitites)

U+22AC, U+22AD, U+22AE, U+22AF (slashed logic signs)

U+22EC, U+22ED (slashed triangle inequalities)
Wow -- I don't even know what field these are used in...
Curious: what is your field Pander?

Please extend support for math operators in FreeSans. It concerns the following ranges:
- U+219A, U+219B
- U+21AE
- U+2274, U+2275
- U+2278, U+2279
- U+22AC, U+22AD
- U+22AE, U+22AF
- U+22EC, U+22ED

These are already implemented for FreeSerif and FreeMono. These can be used by scaling conform other math operators in between these ranges which are already available in all three fonts. Also, the components or other glyphs from which these math operators are composed from are already available as glyphs in FreeSans. Preferably these can also be used in order to construct the missing ghyphs which are listed above.

Implementing this will extend the support of math operators in FreeSerif.
