** Description changed:
+ [Impact]
+
+ fonts-liberation and fonts-liberation2 in bionic have skewed font metrics.
This is causing visible formatting issues in any program rendering text using
those fonts, most notably libreoffice (recent versions fail to build because
some unit tests that check the rendered layout fail).
+ This was fixed in debian and synced in cosmic
(https://salsa.debian.org/fonts-team/fonts-liberation/blob/master/debian/patches/unset_OS2_UseTypoMetrics.patch).
+
+ Backporting to bionic is a prerequisite to backporting a recent version
+ of libreoffice (6.0.6, bug #1785679).
+
+
+ [Test Case]
+
+ See original description (at the bottom of the description) for example
+ text documents and their expected layout when opened in libreoffice.
+
+ A good test case is whether libreoffice 6.0.6 builds successfully (all
+ unit tests pass - some unit tests exercise text layout and they fail
+ with the broken version of fonts-liberation2).
+
+
+ [Regression Potential]
+
+ Rendering of text across a variety of programs (especially word
+ processors and web browsers) should be checked to ensure that this
+ doesn't introduce regressions.
+
+
+ [Other Info]
+
+ This is backported straight from Debian, no Ubuntu-specific
+ modifications.
+
+
+ [Original description]

Ubuntu/Xubuntu 18.04 package includes fonts "Liberation Sans" (etc
"Liberation") with sligtly shrinked font metrics. This issue leads to
all office documents typed in Liberation Sans fonts have corrupted
formatting in Ubuntu 18.04 (but these documents correctly opened in
other OS's, for example Ubuntu 17.10). Documents with corrupted
formatting can not print properly: all paragraphs are shifted up,
embedded tables in text - splitted on page breaks. Document circulation
in system based on Ubuntu 18.04 operating systems temporarily paralized,
because Liberation fonts are basic fonts for open-source document
circulation.
In attachment I have type a example office document with 2 pages and
enumerated strings. On normal ordinary conditions this document have 54
strings on first page and 54 string on second page. But if this document
open in Ubuntu 18.04, it's found than 5 strings from second page moves
to first page. Compare font versions embedded with Ubuntu packages we
can see that versions are different (sudo apr search fonts-liberation*
command):
Ubuntu 17.10 - 1:1.07.4-2, 2.00.1-3
Ubuntu 18.04 - 1:1.07.4-5, 2.00.1-5
I have create a bug 117411 "Font metrics slightly changed after update
OS to Ubuntu 18.04", see
https://bugs.documentfoundation.org/show_bug.cgi?id=117411, but I think
that this bug concerns a Ubuntu/Xubuntu 18.04 package.
