Hello Carsten, others,

(This is supported by B saying "Note that these rules are only valid for ABNF encoded in 7-bit ASCII or in characters sets that are a superset of 7-bit ASCII.”, so these rules appear to have been designed with limited applicability in mind.)

Well, strictly speaking, "limited applicability" isn't wrong. But the 
only serious case of 'character sets' that are not a superset of 7-bit 
ASCII (in the sense applicable in this case) are the encoding in the 
EBCDIC family. So the limitation isn't very serious in practice.

Regards,    Martin.

> RFC 8259 does not define DIGIT or HEXDIG; the assumption here seems to be that those come from the Core Rules.  This does not appear to be said in the document, which maybe is the real errata behind this report.
