$rxTc = '/' .
# Alla tecken som otillåtna tecken är förbjudna.
'[^ %!"$&\'()*,\-.\/0-9:;=?@A-Z\\\\^_`a-z~\x80-\x{10FFFF}+]' .

'|[\xA0\x{1680}\x{180E}\x{2000}-\x{200A}\x{200E}\x{200F}\x{2028}-\x{202F}\x{205F}\x{3000}\x{FFFD}\p{Noncharacter Code Point}]' .
# Starting whitespace/colon or an empty title.
'|\A(?:[ :]|\Z)' .
# Double/closing whitespace.
'| (?: |\Z)' .
# URL percent encoding sequences interfere with the ability to round-trip titles, you can't link to them consistently.
'|%[0-9A-Fa-f]{2}' .
# XML/HTML character references produce similar issues.
'|&[A-Za-z0-9\x80-\x{10FFFF}]+;' .
# Pages with "/./" or "/../" appearing in the URLs will often be unreachable due to the way web browsers deal with 'relative' URLs. Also, they conflict with subpage syntax. Forbid them explicitly.
'|(?:\A|\/)\.\.?(?:\/|\Z)' .
# Magic tilde sequences.
'|~{3}' .
