(As noted below, strings passed to datasend() + should always be encoded first, and therefore not stored in such a state + anyway, but it is all too easy for perl to change this internal state + unless the encodeing is done at the very last minute before calling + datasend(), so it helps if datasend() plays more nicely in this case. In + particular, it was wrong of datasend() to treat upgraded and downgraded + strings differently when their contents were identical at the Perl level.) + + This bugfix results in a breaking change to the case of a "text string" + with characters in U+0080..U+00FF stored internally in an upgraded state + since those characters are likewise no longer encoded to UTF-8 by + datasend(), but callers of datasend() should not have been relying on this + behaviour anyway: In general, datasend() has no idea what encoding is + required for output so callers should always encode the data to be output + to whatever encoding is required first. This has now been clarified in the + documentation. + + Finally, a text string with characters >= U+0100 will now cause a "Wide + character in print" warning from datasend() since such characters cannot + be output as bytes and datasend() no longer encodes to UTF-8. In this + case, UTF-8 bytes will still be output as before since that happens to be + the internal representation of such characters, but the warning is new. + Callers should heed this warning and encode such strings to whatever + encoding is required before calling datasend(), as noted above. + + [Ricardo Signes, CPAN RT#104433] 3.06 2015-04-01 |
