I had this problem that the Dav Backend lost / did not sync Files with a plus sign. I have tested this PR and it fixes it. @icewind1991 @ArtificialOwl @Fenn-CS please merge this. |

PHP's urldecode function does not decode URLs according to RFC 3986, but according to the HTML 4.01 query parameter encoding. This results in pluses being wrongly decoded to spaces even though they should not be decoded at all. Use rawurldecode instead, which follows RFC 3986 properly. This fixes an issue where files on DAV shares containing pluses were incorrectly decoded to spaces. Fixes: nextcloud#15849 Signed-off-by: Lorenz Brun <[email protected]>
