Fixes Macedonian Cyrillic BE in Regular and Bold none

Description Dimitrij Mijoski 2018-05-03 08:58:14 UTC 
Description of problem:
The lowercase BE (U+0431, б ) looks incorrect. It looks like Greek lowercase delta δ. This is related to this change https://pagure.io/liberation-fonts/c/607af724740a2daf868b4d2b731d58bf1f5b46a7?branch=master and bug 657849

While those changes may matter for Serbian, the Macedonian BE in regular fonts actually looks same as the Russian. ONLY in italic fonts the delta look is applicable, because italic fonts kinda look like handwriting.

Note that if you open the page for Cyrillic alphabet or the Cyrillic BE on wikipedia, it states incorrect and uncited info about this, Macedonian and Serbian shape of BE is different.

Version-Release number of selected component (if applicable):
2.00.1

How reproducible:


Steps to Reproduce:
1. Install harfbuzz and liberation2
2. Run the following commands

cd location/of/fonts
hb-view --language=mk LiberationSerif-Regular.ttf б
hb-view --language=mk LiberationSans-Regular.ttf б
hb-view --language=mk LiberationMono-Regular.ttf б

hb-view --language=mk LiberationSerif-Bold.ttf б
hb-view --language=mk LiberationSans-Bold.ttf б
hb-view --language=mk LiberationMono-Bold.ttf б

Alternative way to trigger is to:
1. Open libeoffice (Liberation Serif is selected by default)
2. Write: б
3. Select that and change the paragraph language to Macedonian.

Actual results:
I see the delta

Expected results:
Should have the standard "six" shape, not "delta" shape

cd location/of/fonts
hb-view --language=en LiberationSerif-Regular.ttf б
hb-view --language=en LiberationSans-Regular.ttf б
hb-view --language=en LiberationMono-Regular.ttf б

hb-view --language=en LiberationSerif-Bold.ttf б
hb-view --language=en LiberationSans-Bold.ttf б
hb-view --language=en LiberationMono-Bold.ttf б

Comment 2 Dimitrij Mijoski 2018-05-03 12:11:51 UTC 
I'd say that the delta will surprise even Serbian readers, as pointed here https://ask.libreoffice.org/en/question/60778/problem-with-cyrillic-letter-b-in-linux/

It would be better to completely disable the delta in Regular and Bold even for Serbian until it gets a better shape. It should not look like Greek delta.
Comment 3 Dimitrij Mijoski 2018-05-10 10:37:50 UTC 
If you open official orthography documents of Macedonian and Serbian language, you will see that BE is written with the six look not the delta look.

Here is Macedonian orthography, scroll to page 13/368 http://www.pravopis.mk/sites/default/files/Pravopis-2017.PDF

Here is Serbian orthography, scroll to page 18 http://repo.etfovac.com/srpski-jezik/Pravopis%20MS_2010.pdf

Basically, the delta should be completely gone from the Regular and Bold.
