Hello, sorry for late response. Any url, containing symbol `%`, for example ``` http://example.com/media.m3u8?param=%3D ``` If this url passed to URLBuilder, output will ecape percent sign: ``` http://example.com/media.m3u8?param=%253D ```

For encoding parameters in url it is better to use `encodeURIComponent()` instead of `encodeURI()`. It will also escape `&` symbols.
