Add const in CharCodeToUnicode
I submit this merge request to update some functions that can be transformed to const.
As we discussed on IRC, when we created a charCodeToUnicode structure we can't use non const functions.
In CharCodeToUnicode.h
Functions updated:
CharCode getLength() const
int mapToUnicode(CharCode c, Unicode **u) constIn CharCodeToUnicode.cc
Function updated:
int mapToUnicode(CharCode c, Unicode **u)
