# 1. You have to enable hanging punctuation which is missing in your example.
I used it, it was a miscopying... sorry.
# 2. You have to create your own protrusion vector because the predefined vectors set hanging for hyphens only for the right margin.
Thanks, it works for Czech language. But what has happened is that the
repeated hyphen appears also with languages which do not use it (or for
which it has not been set).
How can I assign the definition only to the selected language?
(I discovered only to put {\mainlanguage[cz]text} into a group...)
%% only a note:
I tried:
\def\mylanguage{cs} \appendtoks \ifx\mylanguage\currentlanguage \setbreakpoints[czcompound] \else \resetbreakpoints \fi \to\everylanguage
\let\ORIGmainlanguage=\mainlanguage
\def\mainlanguage[#1]{\def\langpar{#1}
\def\langpom{cz}\ifx\langpom\langpar\gdef\mylanguage{cs}\else\gdef\mylanguage{\langpar}\fi
\ORIGmainlanguage[\langpar]
}
which repeats only the Czech hyphen but with a side effect -- hyphenated words are not broken anymore in other languages.
What am I doing wrong? Or is there any system solution?

Best wishes,
Tomáš
