Space engineers monospace font workaround

I'm currently writing some ingame scripts in space engineers (vanilla) to show certain data on ingame LCD panels. Besides text I also want to display some diagrams. Unfortunately space engineers LCD panels do not provide monospaced font what makes it quite difficult to generate ASCII art diagrams.

The only way to get what I want is try to find characters that have the same width which is the case for | and ' or for _ and x.

Can anyone provide a list of such equal-width characters? I still did not find any set of 3 chars with same length.

Edit for clarification: I'm not searching for a technical workaround (like replacing the font of the game).
