TrueColor CP437 is an ASCII rendering framework for Unity. It mainly consists in a text console mapped on a polygon. The default character sets are inspired by the original MS-DOS Code Page 437 character set.

Features :

• free size ( not constrained to typical console sizes, like 80x24 for example )
• comes with 3 default fonts : 8x8, 8x14 and 8x16 pixels
• can be drawn into within the Unity3D editor, like you would with any ASCII art editor
• easily programmatically accessed through a simple and comprehensive API
