There could be a technical problem in expressing IDENT using the FLEX notation: it cannot represent characters above 127 (see note at the beginning of G.2). The correct grammar of on nonascii should be either: nonascii 0xA0 .. 0x10FFFF # hexadecimal nonascii 160 .. 1114111 # decimal nonascii 0240 .. 04177777 # octal but none of the above could be expressed using FLEX. Thus the prose in 4.1.3 is the only normative reference. -- Andrei Polushin
