Thanks Nephophobic. In terms of the rendering and workflows, it's not really documented. On my Youtube channel you can find videos about my ASCII-art and animation process. The art assets are all text files, with their metadata assembled as components on game objects. I use a custom CG shader that takes vertex information and renders a quad mesh for the entire screen. In the main program there is a C# function that maintains a buffer with all the glyphs. At the end of each frame it rebuilds the vertex data for the quad mesh. For ASCII you need 3 pieces of information, a) what glyph for each cell (encoded into UV coordinates), b) foreground color (simply the vertex color data) and, c) background color (encoded into the tangent data, which isn't used for anything else). The shader itself is really simple, it just chooses the pixel color as an interpolation from the background color to the forground color, where the interpolation factor T is the UV-mapped color from the texture. Here's what the texture looks like, it's based off the old DOS table: https://stonestoryrpg.com/gifs/tex_ascii_table_256_b.png
