Possible to Un-format text in Wavelab?

I think that’s the best solution for now. You could uncheck “restrict to ascill” on the CD Text window before autofilling the titles, and all will probably look fine in the Text window and CD Report, but will most likely be garbage on the DDP or CD master, and if not, possibly garbage only on some CD players, if it works like accents. So unchecking “restrict to ascii” would probably be a terrible idea.
