ASCII is a subset of all 8 bit character sets used in Fidonet. ASCII is also a subset of the Universal characters set AKA, the Unicode character set. UTF-8 is not a character set, it is a character encoding scheme for Unicode. So are UTF-7, UTF-16 and UTF-32.

There is no problem. Nodelist processors that allow 8 bit values in strings are character encoding scheme agnostic. For them the byte sequence C3 B6 is just two bytes. C3 B6 is the two byte sequence that codes for the o with diaresis in UTF-8, but the nodelist processor does not know that and does not have to know any more than that it has to know that the single byte sequence 41 encodes for the letter A. Nodelist processors do not interpret the byte sequence that encodes the name of a sysop or the name of a city.

Strictly speaking an ASCII only text is UTF-8, but that is not what I meant of course.
