Puh, it's lot's of possibilities to choose of, now... I thought
of something like the foreach-loop but wasn't sure if that is
correct for all utf encodings. All in all, I think I take the
any-approach, because it feels a little bit more like looking
at the string at a whole and I like to use enforce.
Thanks for all your answers!
All the examples given here are very nice.
But alas this will not work with postscript files as found in the
wild.
In my program, I read a postscript file. Normal postscript
files should only be composed of ascii characters, but one
never knows what users give us. Therefore I'd like to make sure
that the string the program read is only made up of ascii
characters.
Generally postscript files may contain binary data.
Think of included images or font data.
So in postscript files there should normally be no utf-8 encoded
text, but binary data are quite usual.
Think of postscript files as a sequence of ubytes.
