Hello.

I received this from the Debian bug system.
I've checked and the current version (1.0.1) still shows the bug.

Subject: wdiff: Does not handle UTF-8 properly

Package: wdiff
Version: 0.5-19
Severity: normal

"wdiff -a" uses backspace and overstrike to provide emphasis; thus, it
will emphasize 'x' by printing 'x^Hx'.  When it encounters a UTF-8
character, it does this for each byte, rather than for each character;
thus, emphasis of <E2><80><99> (U+2019 RIGHT SINGLE QUOTATION MARK)
looks like '<E2>^H<E2><80>^H<80><99>^H<99>', when it should look
like '<E2><80><99>^H<E2><80><99>'.
