I have noticed an error, please can someone with update rights fix it.

https://www.php.net/manual/en/regexp.reference.character-classes.php

7th paragraph contains:

However, if the "]" is escaped with a backslash it is interpreted as the end of
range, so [W-\]46] is interpreted as a single class containing a range followed
by two separate characters.

The word NOT is missing, it should read:

However, if the "]" is escaped with a backslash it is NOT interpreted as the 
end of
range, so [W-\]46] is interpreted as a single class containing a range followed
by two separate characters.
