# Problem with polyglossia behaviour for LuaLaTeX 1.0.4. Possible bug?

With LuaLaTeX I had compiled the same code by different distributions:

LuaLaTeX 0.95.0/TeXLive 2016

LuaLaTeX 1.0.4/MiKTeX 2.9.6236

Unfortunately, I got different results for polyglossia behaviour.

With the following code:

%%============================ Compiler Directives =======================%%

LuaLaTeX 0.95.0/TeXLive 2016 works fine.

But LuaLaTeX 1.0.4/MiKTeX 2.9.6236 produce an error:

! Package polyglossia Error: The current roman font does not contain the Cyrillic script!
(polyglossia)                Please define \cyrillicfont with \newfontfamily.

See the polyglossia package documentation for explanation.


Main question is: Why only with LuaLaTeX 1.0.4/MiKTeX 2.9.6236 should I use any other nonintuitive constructions for using fonts differ from Latin?

Is this a bug of LuaLaTeX 1.0.4?

I note that in selected fonts the necessary symbols are present.

log-file

• The error message is only issued when you add \texttt{...} in a Ukrainian context. And it does also in TeX Live, of course. Solution: \newfontfamily{\cyrillicfonttt}{<some monospaced font supporting Cyrillic>}. I guess some specific MiKTeX configuration file kicks in, but it's unimportant, as the declaration above is needed whenever the font set with \setmonofont has no specific support for Cyrillic. – egreg Apr 24 '17 at 16:54
• @egreg MyTeXLive works fine even with \texttt{...} and the preamble. Just checked – sergiokapone Apr 24 '17 at 16:59
• Then the problem is in the font. Sorry, but I don't have Consolas. – egreg Apr 24 '17 at 17:01
• @egreg I had try \newfontfamily{\cyrillicfonttt}{Consolas} and got the same error with MikTeX. – sergiokapone Apr 24 '17 at 17:06
• @egreg Just cheched xelatex/MikTeX with MWE preamble. Works fine. I think, the problem in MikTeX'sLuaLaTeX – sergiokapone Apr 24 '17 at 17:17

From your log-file one can see that you are using a local version of times.ttf, in E:/Projects/LaTeX/Z_LaTeX_XP/Fizmatlit/localtexmf/fonts/truetype/times.ttf and one can also see that this font doesn't has correct Script features:

. fontspec info: "no-scripts"
.
. Font "TimesNewRoman" does not contain any OpenType Script' information.


So it is quite probable that the font is faulty, and as it is in a localtexmf is is also probable that only your miktex system is using it which would explain why only miktex doesn't work. This types of errors depends normally on a concrete font file, and so can be easily system and font dependant.

works with LuaTeX 1.0.4:

\documentclass{article}
\usepackage[math-style=TeX]{unicode-math}
\usepackage{libertine}
\setmonofont[Scale=0.9,FakeStretch=0.9]{Consolas}
\newfontface\cyrillicfont{Linux Libertine O}
\usepackage{polyglossia}
\setmainlanguage{ukrainian}
\setotherlanguage{russian}
\setotherlanguage{english}

• Yes, with \usepackage{libertine}` very well. But, what if I want to use a system font? (I use Win10) – sergiokapone Apr 24 '17 at 18:38
• You have to use a font which has the cyrillic letters. Times has no one! – user2478 Apr 24 '17 at 19:25
