/**
 * Regexp of all possible ways to write extensions, for use when parsing. This
 * will be run as a case-insensitive regexp match. Wide character versions are
 * also provided after each ASCII version. There are three regular expressions
 * here. The first covers RFC 3966 format, where the extension is added using
 * ';ext='. The second more generic one starts with optional white space and
 * ends with an optional full stop (.), followed by zero or more spaces/tabs
 * /commas and then the numbers themselves. The other one covers the special
 * case of American numbers where the extension is written with a hash at the
 * end, such as '- 503#'. Note that the only capturing groups should be around
 * the digits that you want to capture as part of the extension, or else parsing
 * will fail! We allow two options for representing the accented o - the
 * character itself, and one in the unicode decomposed form with the combining
 * acute accent.
