Hi

Thank you both for your detailed replies. I will proceed carefully.

Edit: I used the first regex with Sigil (it does not work with the Calibre editor). It proceeded about 95% of all entries. The remaining ones had one or more accented letters of some sort (â, é, ë, ê, ô, ç, etc.). But it was easy to correct. No need to adapt the regex.
