In Finnish, HYPHEN-MINUS is a word character, and current OpenOffice.org 
correctly handles it as such (see issue #58513). We have recently discussed 
this at dev@fi.openoffice.org and concluded that the behaviour should be 
extended to cover NON-BREAKING HYPHEN as well.

But after experimenting with such change I discovered that non-breaking 
hyphens are completely stripped from words before they are send to the 
spellchecking component for processing. Steps to reproduce:

- Add [:name = NON-BREAKING HYPHEN:] to $ALetter in 
i18npool/source/breakiterator/data/dict_word_fi.txt and 
i18npool/source/breakiterator/data/count_word_fi.txt

- Enter "Kaakkois-Suomi" in Writer using HYPHEN-MINUS as the hyphen
  -> spellchecker component receives word "Kaakkois-Suomi"; this is OK.

- Enter "Kaakkois-Suomi" in Writer using NON-BREAKING HYPHEN as the hyphen
  -> spellchecker component receives word "KaakkoisSuomi". This is wrong, I 
would expect to get "Kaakkois-Suomi" (maybe with the non-breaking hyphen 
converted to an ordinary hyphen).

It seems like the same bug is present in the hyphenator as well, although 
there it is less likely to cause any real problems.
