 | |
|  * 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.
 | |
|  *
 | |
|  * It was also discovered that versions of the SOGO connector for thunderbird
 | |
|  * has issues with urlencoded colons.
