rpmlint file-not-utf8

[Richard W.M. Jones]

I'm getting warning below from rpmlint about "file-not-utf8".

cduce-devel.x86_64: W: file-not-utf8 
/usr/share/doc/cduce-devel-0.5.0/tutorial_getting_started.html
cduce-devel.x86_64: W: file-not-utf8 
/usr/share/doc/cduce-devel-0.5.0/manual_expressions.html
cduce-devel.x86_64: W: file-not-utf8 
/usr/share/doc/cduce-devel-0.5.0/AUTHORS

The AUTHORS file is fair enough - I can use iconv to convert that to 
UTF-8.  However I'm concerned about the HTML files.  These are 
ISO-8859-1 files, and moreover they contain correct Content-Type 
metadata to mark them as such so I can't see there is a problem with 
these two files not being UTF-8.

Do I need to worry about it?

Rich.
