Supports ALL ASCII characters. Basically, all characters on a standard multilingual smartphone keyboard. You can see which characters are supported by checking out the costumes list. Just ignore the first 3 costumes ;) Yes, I added all 263 costumes by hand. Yes, it was a very tiring process. In this project, you can store 405,000 characters of ASCII in a single costume. Then, you can read it back. This is useful for bypassing Scratch's list limitations, letting you store 4.05KB of list data per costume, then decoding it back and filling the list on the viewer's end. This would be useful for things like dictionaries. Just one issue is that I've added no compression, so if you want that it's up to you to figure it out for yourself. Additionally, the resolution is 180x180, but I've tested SOME computers don't work with 180x180. If this is the case, you can decrease the RESOLUTION variable. If you want some random examples, go here: https://www.random.org/bitmaps/?format=png&width=180&height=180&zoom=1 and download the image, load it into the project and skew it so that the image is spread over the full stage. Make sure that you keep the resolution in the project as 180.
