discogs web sources script fails on utf-8 names with spaces

I use discogs.src from v2.42 installer, without any modification.
If i request artist with any non-latin characters in its name starting with small names or with mixed case ( like гости+из+будущего ), script fails with message "Error connecting to server: www.discogs.com". It happens because of all words with non-latin characters in discogs urls should start with capital letter like this one: Гости+Из+Будущего. Is it possible to fix case of text retrieved from user?
Thanks ahead.

You can edit the script and change
[SearchBy]=%artist%
to
[SearchBy]=$caps(%artist%)

But it will only capitalize if your artist tag is filled, not if you type it in the search box.
