Bug #76885 for Data-ICal: Folding may split multi-byte characters

Subject:	data::ical folds lines with utf-8 sequence at position ~75 wrong

Hi, Data::ICal::Property's folding algorithm (in private method _fold) seems to assume that all content is US-ASCII as the folding happens at 75 bytes no matter what. This assumption becomes a problem when at position 75 there is a UTF-8 sequence (double byte) which may not split onto two lines. It would be nice if folding were a bit smarter. Thanks ;-) Kaj

I had the same problem, but it turned out to be because Perl didn't know that my strings were utf-8; when I fixed that, folding worked fine. (I had to add pg_enable_utf8 to the DBI-connection I am reading my data from - maybe you need something similar?) Best regards, Adam

I'm rejecting this bug. If you pass bytes, Data::ICal does not have a means to know how they are encoded. If you pass characters, they can be properly split.
