This code:

$user_id = get_current_user_id();
$input = 'double ' .chr(92) . chr(92) . ' slashes';

update_user_meta($user_id, 'update_meta_bug', $input);
$output = get_user_meta($user_id, 'update_meta_bug', true);

if ( $output != $input ) {
  echo '<b>$output != $input</b>';

Produces this output:

$output != $input

Thanks for the report, @ericscheid . The meta functions expect slashed data. Yes this is nasty, but that's the unfortunate position we're in. You can pass the value through wp_slash() before passing it into this function.

This is not very well documented. See #41593.

Thanks John.

This is not very well documented. See #41593.

An unenviable tech debt.
