Hi,
It seems that perl regular expressions lost one polish letter (ą):
https://www.compart.com/en/unicode/U+0105
I can see this problem only under OpenBSD 6.7 with php-7.4 (same version
of php under linux is OK)
Ex.:
PHP 7.4.10 or 7.4.5
<?php var_dump(preg_match('/^.{5,64}$/', 'daswęzdas'));
int(1) // OK
PHP 7.4.10 or 7.4.5
<?php var_dump(preg_match('/^.{5,64}$/', 'daswązdas'));
int(0) // UPS???
PHP 7.3.21
<?php var_dump(preg_match('/^.{5,64}$/', 'daswęzdas'));
int(1) // OK
PHP 7.3.21
<?php var_dump(preg_match('/^.{5,64}$/', 'daswązdas'));
int(1) // OK
Any ideas how to fix that?

The same happens with any UTF-8 sequence that ends in 0x85. I guess (a
part of) PHP's PCRE code is not in UTF-8 mode, causing triggers on
CHAR_NEL (=0x85).
for ($i = 0x75; $i <= 0x825; $i++) {
$u = mb_chr($i);
$str = 'dasw' . $u . 'zdas';
$r = preg_match('/^.{5,64}$/', $str);
if ($r == 0) {
printf("%04x:", $i);
for ($j = 0; $j < strlen($u); $j++) {
$b = ord(substr($str, 4 + $j));
printf(" %02x", $b);
}
printf(": %s\n", $str);
}
}
