Item3698: Undefined subroutine &utf8::is_utf8

My system is on Perl 5.8.0. If I change the version number from 5.008 to 5.008001 in lib/TWiki/Store/RcsFile.pm it works again:

        # remove utf8 encodings from filenames
        if( $] >= 5.008001 ) {
            utf8::downgrade($this->{attachment}) if $attachment && utf8::is_utf8($this->{attachment});
            utf8::downgrade($this->{file}) if utf8::is_utf8($this->{file});
            utf8::downgrade($this->{rcsFile}) if utf8::is_utf8($this->{rcsFile});
        }

Possibly better to check for the existence of the module instead of the Perl version number?

I think I will remove this feature from Patch04x01. Steffen had concerns about it also. I think we need to understand the whole utf8 thing better and implement a safer solution to the problem. It does not help creating a new problem to fix another problem.

Reverted out of Patch04x01 and MAIN.

Closing this report and reopening the original report.
