*
|
|
* It was not possible to use PHP's built-in methods for this, because some clients don't like
|
|
* encoding of certain characters.
|
|
*
|
|
* Specifically, it was found that GVFS (gnome's webdav client) does not like encoding of ( and
|
|
* ). Since these are reserved, but don't have a reserved meaning in url, these characters are
|
|
* kept as-is.
