Fix bug causing "|" to encode as apostrophe (#35)

These regexes use both square-bracketed character classes and the `|`
operator at the same time, when they only actually need to use one or
the other. Since `|` doesn't mean anything special inside a character
class, this causes literal `|` characters in clues to be converted to
apostrophes.
