@Pearlseattle, that I can't do straight away since the code for all this is in a migration tool that does the job. I can look for it but as it seems I do not need any help anymore......
I figured it out. There was a checkbox that I could untick to NOT make some convertion "if special characters" seemed weird as the did.
I missed this all the times I tested the migration tool but last night I saw it and that made it all good.
Now the "small" job is done, the big one is for me to manually try to convert all pictures that some addon created links for in the old software and this tool is not available in the new forum software but that is another story that won't bother you with (maybe
)
