URI encoding in the svg function results in a broken data URI

[PitchforkAssistant]

The svg helper function calls encodeURIComponent on the provided SVG before returning it. Based on the comment above the return line, that appears to be intentional as a fix for some different issue. Encoding the data like this completely breaks the data URI, resulting in a missing image placeholder on both Shreddit and the Android app (iOS untested).

If the point of the URI encoding is to avoid issues with special characters, perhaps it would be best to instead encode it as a base64 string? From testing with local modifications, changing the return line to this appears to work as far as the SVG actually showing up is concerned:

return `data:image/svg+xml;base64,${Buffer.from(str).toString('base64')}`;
