Hello,

all I could find about this issue was the explanation in the thread
linked from my message. The description of the cause goes like this:

"I found why this error happens. In the recent CVS Emacs, as
utf-translate-cjk-mode is on by default, some Unicode characters will
be decoded into one of CJK character set. But, as
xsdre-range-list-to-char-alternative (xsd-regexp.el) simply do
something like this to generate a character range: (format "%c-%c"
(decode-char 'ucs FROM) (decode-char 'ucs TO)) the resulting regexp
causes the above error."

The patch below is supposingly fixing this issue (and is working for
me). However, I guess we need someone to verify this since the
original maintainer is currently not available. Could someone look
into this and suggest whether this is the right solution?
