In my TagManager I have tags like:
The first one, accessibility, uses an icon I downloaded from morosanuae.github.io/tw-icons, the other one, gym, is a emoji I copied from emojipedia.org or I typing on a keyboard with support for emojis.
Create the Icon
First, you have to create a tiddler with similar to this:
$:/images has to be there. The unicode part of it is for my own understanding.
Eventually, in your filesystem, it creates a file
wiki/tiddlers/$__images_unicode_gym.tid like this:
created: 20210802195500933 creator: dmitryrck modified: 20210802195507116 modifier: dmitryrck tags: title: $:/images/unicode/gym type: text/vnd.tiddlywiki 💪
Set the Icon on the Tag
You can either use the TagManager like this:
Or you can open the tiddler of that tag:
If the tiddler of that tag does not exist, just create it.
