The Localize Media addon is not working for urls containing %3F (encoded ?) e.g. the url: https://xeno-canto.org/sounds/uploaded/CDPSJSQTQZ/XC439782-Piusa%20Heidelerche%20%3F%20180527.mp3 returns 404 with the addon, but works fine in a browser.
The same thing happens if it contains %23 (encoded #) e.g. https://xeno-canto.org/sounds/uploaded/VSXHBVQJDA/XC298358-Locustella%20lanceolata*26xi13_620%23451.mp3
I find the addon very helpful, so I hope this can be fixed.
