I have a program that reads and writes (among others) strings that
should be utf8 encoded. I say "should", because somewhere deep
inside the dark corners of that program, sometimes, the utf8 flag on
a string is lost. (I'm still investigating where, tips to attack
such a problem are welcome.)
When writing the string, the program clears the utf8 flag
and writes a simple string of octets using:
$s = encode("utf8", $s) if $s =~ /[^\x00-\x7f]/;
$n = length($s); # yes, we need length in bytes
...
print $s;
Why would someone test for pure 7-bit strings instead of:
$s = encode("utf8", $s) if Encode::is_utf8($s);
which seems superior to avoid double utf8 encodings,
should the utf8-flag be lost. And it's faster.
Or even simply: Encode::_utf8_off($s)
The problem is that I'm usually wrong. Am I this time?
Am I missing something? Or do I need more coffee?
