AdditionalSymbols not working

[kelmi92quo]

AdditionalSymbols are never detected as hastag, due to this line of code:
HashTagHelper.java, lie 136:
if(sign == '#'){
startIndexOfNextHashSign = index;

            nextNotLetterDigitCharIndex = findNextValidHashTagChar(text, startIndexOfNextHashSign);

            setColorForHashTagToTheEnd(startIndexOfNextHashSign, nextNotLetterDigitCharIndex);
        }

It only compares with '#'
