[pcre-dev] About \x{}

Hi,

     l meet a problem when using the character \x{} without UTF-8 supported.

For example, l use the pattern /\x{c6d0}/,but there is always an error,
\x{...} sequence is too large. So, is there some way l can use the pattern
like that without UTF-8 supported when the value is greater than FF?

     I hope to have a letter from you before long. Thanks.
