"Error: Non-hex digit used for Unicode escape"

"Error: Non-hex digit used for Unicode escape"

[Andrew M. Scott]

I downloaded Ilya's latest (v5.19) cperl-mode.el from
http://math.berkeley.edu/~ilya/software/emacs/cperl-mode.el.5.19.bz2
today.

bunzip2'ing and byte-compiling it on a June 21, 2006 Emacs CVS
snapshot and build gives this error in *Compile-Log*:

cperl-mode.el:8825:1:Error: Non-hex digit used for Unicode escape

I then tried some older CVS Emacs builds. I see the error beginning in
my June 12, 2006 CVS build but *not* in my June 8, 2006 CVS Emacs
build.

Cheers,
Andy Scott

That version of cperl-mode.el needs this patch:
