For some reason, in some circles, it seems to be semi standard to use þ (0xFE aka thorn) as the delimiter and a paragraph symbol (0x14 aka DC4 aka ^T) as the separator. The latter is not to be confused with 0xB6.

Anyway, these character are presumably not going to occur in ordinary text.

All of "upper ascii half" can occur in ordinary text in "pre-Unicode" encodings.

0xFE is a good example - you may get a customer or employee from Iceland with that character in their name (e.g. https://en.wikipedia.org/wiki/Haf%C3%BE%C3%B3r_J%C3%BAl%C3%A...), or data in cyrillic cp1251 or koi8-r enconding where 0xFE also represents characters that you'll encounter in surnames, etc.

It would be escaped in that case.
