I don't see what I'm looking for in either the hinted or unhinted
fonts in noto-fonts on github.


It seems a bunch of symbols were moved from Google's noto-fonts
repository into noto-fonts-alpha around commit
bc9353da6f625b7a47035de952c2e8fd9e3ae889 (in noto-fonts). I think this
is really a regression, and shouldn't have been pulled into Debian.
Symbols that were previously in "NotoFontsSymbols-*" are no longer
found in noto-fonts, but are in noto-fonts-alpha.

A list of the glyphs I am using, which are no longer found (with some
exceptions scattered about) in the .deb (probably not the complete
set, just what I noticed):

I feel that Debian should go back to the previous version of the
NotoSansSymbols* files, but I understand that needs to be balanced
against the additional work/problems with packaging an older version.
The symbols I have listed are probably not used by many, but on the
other hand users probably expect a relatively complete set of symbols
from noto ("no tofu").


For my purposes I can get what I need from the following unhinted
files in github/noto-fonts-alpha:
NotoSansSymbols-Regular.ttf
NotoSansSymbols2-Regular.ttf
NotoSansMathGX.ttf
which is a bit more work for me, but not too bad.

Thanks,
Ciarán
