php - Add a semicolon to the Codeigniter permitted URL chars -

i need add semicolon (;) codeigniter permitted url chars pattern, here code:

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_-'; 

i need add semicolon (i need because semicolons passed url), don't know how add pattern.

thanks in advance!

you many not use semicolon's in url except it's intended purpose.

can url contain semi-colon?

does not work?

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_-;';
