From my reading you can use any valid non-ascii character for the initial one too: ident [-]?{nmstart}{nmchar}*
nmstart [_a-z]|{nonascii}|{escape}
nonascii [^\0-\177]
unicode \\[0-9a-f]{1,6}(\r\n|[ \n\r\t\f])?
escape {unicode}|\\[^\n\r\f0-9a-f]
nmchar [_a-z0-9-]|{nonascii}|{escape}
(nmstart being the key definition for this point) |
