Yes, the document I attached was generated from the text editor on Ubuntu (whatever that is) by the cups pdf creator. It contains the alphabet in upper and lower case, numbers and all standard (on the keyboard) characters. > >> A pdf file that shows this behavior is attached.

We can add new text in a new system font. This is inconvenient, as it means guessing the original font, retyping the text, and probably increases the file size by slicing in a new font. > >> >> (I am sorry if this has been covered already: I browsed through the >> support mailing list and could not find anything, and the sourceforge >> list search appears to be broken.) > > We have some reports about problems with accent characters as well as > problems with editing some text exported by OO.
