Very helpful indeed !
Always learning :-) I did not know that a non-breaking space was
considered as a word !
Like St Thomas, I tried it and … you are right (of course ;-))
Yes, as you say, it is unlikely (mainly due to the fact that one use
two keys to type a non-breaking space)
but sure your function trim is a prudent precaution.
Thanks a lot Ken
