The problem i had quoting the unexpected character is that, depending on the font settings, it can be very hard to spot what is the offending character when it is a symbol like ' or ". For example, in the following screenshot i have problems seeing the ' character in "'":

Having the character alone at the end removes that kind of problems:

Do you want me to keep the quotes around the character?
