Prevent invalid range offset

[shadowhand]

Errors seen:

Warning: preg_replace(): Compilation failed: invalid range in character class at offset 12 in vendor/str/str/src/Str.php on line 1940

Solution: always place - at the beginning or end of expressions to prevent PCRE from interpreting the character as a range.
