Regexp issues

[mollerhoj]

I'm getting errors because the regexp engine interprets parentesis: "unterminated subpattern" and "unbalanced parenthesis".

I'm analysing very large amounts of text, so not sure how these were triggered.

@mollerhoj If you can provide an example that would be helpful to debug the issue. I most likely need to use re.escape in replace_period_of_abbr function for those kinds of edge cases
