What type of encoding do these ANSI artworks use?

I've found [this website](https://fuel.wtf/packs/fuel27/) ; it has zip files (links on [the main page](https://fuel.wtf/)) with all the artworks. Some of them have an .ans extension and they look like ANSI escape codes used on Linux/Unix, but when I open one of them using cat in the XFce terminal it produces garbage (but in color). They don't look like the image gallery. The first line of the main artwork from the link looks like this (copied from Emacs): [0;1m[30mthere is no substitute [0;33mÜܲ[1;43m°±²²[40mÛ[43mÛ²±[0;33mÝ ßÜ[1;43m²²²[40mÛÛ²[40m[K The file type is DOS, but they can be just created on Windows. When searching for ANSI art I also found [this website](http://www.roysac.com/roy_bestof.html) that has zip files containing only files with an .ans extension and they also don't render properly on Linux (gallery on page 2). My questions are: * what type of encoding is this, for what computer? * do I need a special viewer to see it on Linux terminal? * do you know if this type of artwork was created for Linux/Unix terminals? I've only found ASCII art. * is it possible to convert it to be viewed on Linux terminals?
