What if language grammar allows to put 2 different marks at one word?

What if language grammar allows to put 2 different marks at one word? For example: language allows to put questional mark at any letter of word, and that word is the last one in sentence? That means the label for word must be ?.O, but is it possible? Is it allowed to add a label like that (?.O) in the labels.txt file? Will it work?

I believe It's not. You better use some exclusive symbol for that and do simple postprocessing replacing this symbol with the needed combination.

Ok, but what if the same word at the end of the sentence containes 2 punctuation marks (? and .)? Will this work for training?
