Under Linux Debian, drag and drop of a filename to an FLTK widget
fails if the pathname contains non-ascii characters
because the filename does not arrive as a correct UTF-8 string.
Notice that drag and drop of non-ascii text, as opposed to pathnames,
works well under Linux Debian.
To reproduce:
- create on your desktop an empty file named "téléphone"
- run the editor demo program
- drag the "téléphone" file from your desktop to the editor window
you see
file:///home/<username>/Desktop/t%C3%A9l%C3%A9phone
in the editor window
instead of the expected
file:///home/<username>/Desktop/téléphone
It happens that the pathname arrives UTF-8 encoded, but with
non-ascii bytes replaced by the 3 ascii bytes %XY where XY are the
hex byte value.
The attached dnd.diff patch fixes this for Linux/Debian by
replacing, only when the dnd data begins with "file://", all %XX
instances by the corresponding single byte value.
Is this fix acceptable, or do other Linux/Unix systems, or X servers,
or file managers behave differently with dropping non-ascii pathnames?
If have no access to other X11 systems for tests.
