Thanks for the clarification.

From your description above, it seems this issue is not simply a matter 
of picking different fonts from within same upstream source, as I had 
previously hoped, but instead a matter of upstream removal (deliberate 
or accidental) and alternate shipment of same glyphs as part of a 
_separate_ project.

It seems too cumbersome to me to try circumvbent upstream 
prograssion(/regression) by cherrypicking parts from an older release.

I welcome you to raise this as an issue upstream, ideally to make them 
correct the error, but alternatively to at least have an explanation 
from them on the reasoning for their decision - which might affect my 
opinion on the sensibility of circumventing them, time will tell...

It might make sense to package github/noto-fonts-alpha

I can suggest that you file a so-called "RFP" (request for packaging) 
bugreport if you want to encourage Debian packaging that separate font 
project - am am hesitant to take on that task myself, however, judging 
simply by tha name: Indicates being a staging area of too weak quality 
for inclusion in Debian.

I'll leave this bugreport open for now, but will likely close it as a 
wontfix depending on progress in above suggested areas.


Kind regards,

 - Jonas

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

Hi Ciarán,

Thanks for a well-written bugreport!

Upstream collection of Noto font files include some available both 
hinted and unhinted, and my packaging routines for Debian simply skips 
the unhinted files where both hinted and unhinted exists, by the 
assumptions that the unhinted files contain no additional information 
but are only slimmed down versions of the hinted ones.  Maybe that 
assumpltion is wrong.

Since you mention previously using unhinted fonts, could you please try 
fetch the current _unhinted_ fonts from upstream and check if the 
symbols are missing there as well?  If so, then we should maybe consider 
packaging the unhinted fonts too.

Bug#892226: fonts-noto-unhinted: mathematical and arrow symbols missing, that existed previously

2018-03-06 Thread Ciarán Power 
Package: fonts-noto-unhinted
Version: 20171026-2
Severity: normal
Tags: upstream

Dear Maintainer,

I used the "Noto Sans Symbols" font last year (I think on Debian stretch, but 
I'm not sure) to generate png output using libmakick++. It worked fine for 
various arrow and mathematical symbols e.g.:
the integral symbol: ∫ (U+222B INTEGRAL)
rightwards double arrow: ⇒ (U+21D2 RIGHTWARDS DOUBLE ARROW)

I wanted to make some changes, and noticed that I now get empty rectangles in 
my output, where I had symbols before.

I tried using "gnome-thumbnail-font" and "font-manager" to search for these 
symbols, but was unable to find them.

I looked through the archive of fonts-noto on snapshot.debian.org*. 
fonts-noto-unhinted_20161116-1_all.deb seems to contain all the symbols I was 
using in "NotoSansSymbols-Regular.ttf". The current symbols ttf 
(NotoSansSymbols-Regular & NotoSansSymbols2-Regular) don't seem to contain them.

*http://snapshot.debian.org/archive/debian/20171029T215600Z/pool/main/f/fonts-noto/


I think this was broken by commit bc9353da6f625b7a47035de952c2e8fd9e3ae889 in 
https://github.com/googlei18n/noto-fonts. I don't understand how google's 
noto-fonts is organized, but it seems that a number of useful symbols were 
dropped in this commit.


These are my installed noto fonts:
ii  fonts-noto-hinted 20171026-2
  all  "No Tofu" font families with large Unicode coverage (hinted)
ii  fonts-noto-mono   20171026-2
  all  "No Tofu" monospaced font family with large Unicode coverage
ii  fonts-noto-unhinted   20171026-2
  all  "No Tofu" font families with large Unicode coverage 
(unhinted)

Thanks,
Ciarán
