Please let me know how that goes. FYI, Debian Sarge ships with perl
5.8.4, but it isn't too hard for us to track some other version of
perl, including perl 6.
Have not messed with perl 6. I do not think there will be any
differences between 5.8.4 and 5.8.6. The difference I saw were
between 5.6.1 and 5.8.x. I discovered that I had to enable
warnings (via the warnings pragma) to get perl 5.8 to be more
strict about utf-8 decoding. 5.6.1 was strict by default.
There is also some other minor subtleties, which I belive I have
dealt with.
Is it wise to suppress the malformed utf-8 warning messages? If
mhonarc can deal with the sequences in a proper manner, I'm not sure
if there is any value in printing the warnings.
Good question. I generally don't like to have common-but-harmless
warnings in log files, lest they obscure more serious problems.
But I'm also quite capable of doing my own filtering. For example,
I checked into CVS a new CharEnt.pm that suppressed the warning
messages, along with converted malformed sequences into "�",
according to Unicode recommendations.
I was even able to beef up the <=5.006 code to be more robust about
malformed sequences.
If you want to try it out, grab the next snapshot build, or you
can download the file from the newly added CVS source browsing at
<http://www.mhonarc.org/cgi-bin/viewcvs.cgi/*checkout*/mhonarc/MHonArc/lib/MHonArc/CharEnt.pm?rev=1.16>.
I currently filter out mhonarc's unrecognized character set warnings,
since they are common and there's not much I can do about them.
See the CHARSETALIASES resource.
