Custom field link doesn't correctly handle control characters

Problem/Motivation

For a views field, enabling Output this field as a link and setting Link path to something like:

my-custom-path?one=[field_value_one]&two=[field_value_two]

Can result in broken links due to handlers/views_handler_field.inc > views_handler_field::render_as_link() not correctly determining the correct $path when the query string has control characters, for example tabs.
This is because parse_url() will replace control characters with _, which isn't considered when $url['query'] is used later on.

Steps to reproduce

• Add a views field with custom link that includes a query string that uses values from other fields
• Other fields have control characters, for example tabs
• Observe link is broken

Proposed resolution

Correctly determine the path.
Current code:

$path = strtr($path, array('?' . $url['query'] => ''));

Possible solution:

$path = strtok($path, '?');
