Comment 11 for bug 1051955

Calc doesn't handle all alternative hyphenation patterns of the recent hyphenation dictionaries. Catalan, Hungarian, maybe recent Dutch, Norwegian, Sweden.

Catalan „paral·lel” -> bad „parall=lel”, instead of „paral=lel”
Hungarian „asszonnyal” -> bad „az=szoy=nyal”, instead of „asz=szony=nyal”

This is the root of the following problem, too: (depends from the version of the hyphenation patterns and LibreOffice).

IT-department -> ITT=department, instead of „IT=department”
