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.
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.
* New: support also utf8 (working around false positive test in "inputenc.sty").
* Do not force the change of input encoding to "ascii".
Deny compilation with XeTeX if a document uses TeX fonts and a non-supported input encoding.
* some Japanese (platex) documents fail with inputenc "utf8-platex"
(missing characters in non-Japanese text parts), because the
Unicodechar definitions from "inputenc" are not used.
* some Japanes (platex) documents show wrong output with "auto",
because platex ignores the encoding switch for text parts
in other languages.
* Japanese Beamer documents must set default output to "pdf",
because dvipdfm(x) produces wrong output with document class "Beamer".
* update tagging/inverting rules.
* use HE8 font encoding for Hebrew in language test.
The cls is obsolete, so all PDF exports are disabled. We keep the
1.6.x and 2.1.x tests because those only check roundtrip
convergence, and do not export to PDF.
It used to give an endless loop, so we "ignored" it (did not run the
test). Now it gives a lyx2lyx warning, which is reported at #11455,
so it is appropriate to invert the test.
