Description Johannes Zarl-Zierl 2020-07-24 23:34:30 UTC 
SUMMARY
Non-ascii characters in XML attribute names need to be escaped. This is done in the method FileWriter::escape().
Unfortunately, this function is not fully unicode aware, leading to multiple code points being escaped to the same value. E.g. both "😃" and "⌘" are escaped as "_.0". This could lead to ambiguities if two category names just differ by one character that is mapped to "_.0".
