As Mojca said, without the shadow of a doubt. Just use a single file
as the source, and generate both versions with a simple script. In this
particular case the source file can be the full UTF-8 pattern set, so
the file for pdfTeX can be ignored by applications not interested in it.
Or we can use the current file and generate the UTF-8 file with tone
marks out of it.
