Thanks to Jürgen, who mentions the following:
luaotfload does not find "DavidCLM". In fact, at least on my system,
there is no such font, only "DavidCLM Medium" (and other shapes). This
one is found. Apparently, luaotfload cannot infer from the one to the
other.
As opposed to LuaTEX, XeTeX also queries TEXMF so maybe it just finds
its font there.
In many cases, round trip with older formats involves exporting ERT
or preamble code in the backwards conversion. In the forwards
conversion, if this code is not parsed, often errors can result.
However, in many cases, especially for older formats, it might not
be worth the time or code complexity to address these cases. Such
tests are labled "ertroundtrip".
This commit also inverts a currently failing lyx22x test under the
label "ertroundtrip" since the above paragraph is my best guess as
to why that test is failing. It is likely not worth the time to fix
it, especially since the APA7 layout wasn't even shipped for LyX
2.2.x.
* invert failing lyx2lyx tests for ko/Welcome
* add dedicated test sample
* set language for English text part in ko/Welcome.
Also
* fix a lyx2lyx language test sample
* fix clause in unreliableTests
This happens with "inputenc: auto-legacy" if a language with default
encoding "utf8" (e.g. Turkmen or Mongolian) is used in a Quote
(or another environment).
Debian stable ships now TL18, we don't need to care for older TL versions.
Make CJK-ko documentation more robust (failed with non-TeX fonts and XeTeX,
if LatinModern is not installed system-wide).
The test sample for LyX bug 3059 triggers an error only with
"fontencoding auto-legacy" and can be safely ignored with non-TeX fonts.
Simplify user preamble.
Use common test document for Xe- and LuaTeX with polyglossia
and special one for languages only supported by XeTeX.
Update tagging patterns and comments.
LyX follows LaTeX in dropping support for this combination
(it only worked by tricking "inputenc.sty").
There is no known case where this combination is required or helpfull.
For power users with special needs, XeTeX + TeX fonts is still
available after setting the input encoding to "ascii" or "utf8-plain".
See also #10600.
Amends 7bb30286.
Tested cases are now handled fine.
(There are still many cases where the language support emulation
is too complex for lyx2lyx and manual fixes are required after
lyx2lyx conversion.)
Encoding cp858 supported by only some iconv variants.
Most users will want to change their "encoding" setting instead
of installing/recompiling "iconv" to support this legacy encoding.
ctests are likely will fail with either "vanilla" or "enhanced"
iconv and test a situation that is unlikely to change generally,
so we ignore this test now by default.
Separate xetex-inputenc test sample in working and non-working parts.
Sort HTML-only tests.
Update tagging and ignore-rules.
Change inputencoding to utf8 in dedicated tests (get pdf4_texF working).
* do not ignore Japanese (platex) with system fonts.
* CJK can be used with XeTeX and TeX-fonts if the input encoding is utf8.
do not ignore.
* TODO: set non-TeX fonts and uninvert where possible.
Fixes wrong and missing characters in text parts in other languages
(platex does not support "inputenc").
Fixes compilation errors due to desynchronized encoding switches.
