Fix: Allow brackets and en dash Unicode character in name and comment…

… fields

Allow users to add curved brackets for name fields like target name.
This seems to have worked before the pcre2 adjustments.

Additionally allow the en dash Unicode character (U+2013) for name and
comment fields.

Closes #89
