Go to the "Edit symbol" context menu option and copy/paste the symbol you want from this site: http://unicode-table.com/en/sets/animals/
... Or this site: http://community.giffgaff.com/t5/Tips-Guides/Unicode-characters-to-copy-and-paste/td-p/1978667 (Or use Google to find more characters)
Even though your text editor won't display it, Rainmeter will still show the symbol on the screen!
You can change the font size, color, number of bands, and number of displayed "levels" through the "Edit variables" context menu option
When launching the skin for the first time, the number of horizontal characters is automatically adjusted based on your computer's CPU usage
You may have to manually adjust the "CharacterWidth" option if your chosen symbol is trimmed at the skin boundaries
The Update frequency is 80 by default (Fastest is 16), but at the expense of performance you can change it through the "Edit skin" context menu option
You may have to refresh the skin at least three times when you change the number of bands
This is because every character is a String meter -- Because emoji are not fixed-width and messes up padding
The meter sections are dynamically generated as separate files to be included in the skin
The included font in the download is Symbola by George Douros
