<pre>Per RFC 3986, 'Scheme names consist of a sequence of characters beginning with
a
letter and followed by any combination of letters, digits, plus ("+"), period
("."), or hyphen ("-").' However, the is_file_url_or_path() function in
xdg-open relies on the following regular expression to identify valid URI
schemes:
^[[:alpha:]+\.\-]+:
Not only does that fail on URI schemes that contain numbers (such as h323,
irc6, pkcs11, tn3270, etc.) it also incorrectly identifies strings beginning
with + . or - as valid URIs.
I propose the following replacement:
^[:alpha:][[:alnum:]+\.\-]*:
This bug is present in the most recent version of xdg-open in git.</pre>
