When a post includes a literal backslash, followed by an apostrophe, the literal backslash is removed. This only occurs if auto-links are enabled for the content-type (posts, blog comments, etc).
Fixed for the next release. In
vault/class/bbcode/autolink.php, find (note the backslash working):
Code:
$input = str_replace($hash, str_replace("\'", "'", $replace), $input);
Replace with:
Code:
$input = str_replace($hash, $replace, $input);
While the auto-linker does escape apostrophes, making backslash removal necessary, this particular line is recursive. Since the extra backslashes are already handled during obfuscation, this line from the restoration can ignore them.
