Hello!
In Ukrainian language there are two kind of quotation marks: «…» and „…“ (note difference with English “…”).
According to most recent standards, «…» is main and „…“ is secondary (e.g. «He said „hello!“»).
However, with document text being marked as Ukrainian, neither style is used (straight quotes “…” are auto-corrected to English “…” instead). Auto-correction still works OK for German, Russian and other languages.
Probably default setting for Ukrainian is wrong.
