Files with strange characters do not show up, URL-encode inserted URLs

Files with strange characters will not properly display when inserted into the body textarea because they need to be URL encoded. For example a file with the name file #2 ? something & else.png needs to be encoded to have the URL file%20%232%20%3F%20something%20%26%20else.png, otherwise it will not show up on display.

Of course as usual this problem can be prevented by installing Transliteration and removing these unsafe characters from the file name entirely.
