[canonical - rebuilt] Hyphenation - état des lieux and improvement

[piconti]

Some hyphenation has been handled in some importers, however, not thoroughly in new importers and mistakes remain (eg. for words that.

It could prove useful to to a round check of this in the current importers, canonical and rebuilt data to know which importers should be corrected or enhanced with this.

Action items would be:

• Look at code to see which importers seem to handle hyphenation of words, which don't
• Identify if bug or problems remain fr those which handle theses cases
• Debug the current hyphenation approach for any importer that has bugs remaining
• Implement hyphnation approach on the basis of the first one for any importer not handling hyphens.
• Test/debug for the new importers.
• Comment added function
• Update documentation accordiningly if needed.
