Hi. The script cannot display thumbnails when channel display names contain non-ASCII characters (such as Chinese or Japanese, e.g. 超負荷(sam1268)), because it extracts the channel name from the displayed text instead of from the URL.

So I changed this:
const channel = element.querySelector("[title]").textContent.toLowerCase();

to this:
const linkElement = element.querySelector("a[href^='/']");
const channelUrl = linkElement.getAttribute("href");
const channel = channelUrl.split('/')[1].toLowerCase();

This version extracts the channel ID from the href URL instead of the displayed name, which makes it compatible with all character sets.
