Unesco reports that Croatian Braille swaps the Serbian quotation marks for parentheses and the period/full stop for the apostrophe, but it's possible that this is due to a copy error; the table below follows Croatian Wikipedia, which agrees with Serbian, for these characters.[1] There is less punctuation reported for Slovene and Macedonian Braille, but what there is matches Serbian conventions.
The superscript is reported for Croatian Braille; in Serbian Braille, ⠌ is used for the virgule /. In Slovene Braille, the emphasis (bold/italic) marker ⠸ is reported to be an abbreviation sign.
Croatian Wikipedia states that ⠠ is used for capital letters.

^ abcdeThe Croatian apostrophe ⠲ is unusual by international standards, and it is possible the period and apostrophe were swapped in a copy error by Unesco (2013) and copied from them to other sources. Croatian Wikipedia gives ⠲ for the period and ⠶ for parentheses, both agreeing with Serbian Braille.
