I'm sure this has been asked multiple times, but I couldn't think of the right combination of keywords to find it.
I never bothered with learning about memory stuff, but for efficiency I might need it.

This is sitelen pona, a writing system I am planning to use for a game. A glyph is 7x7(8x8 including borders), and so far I have a total of 132 characters.

I would like to know how I could

• efficiently store the glyphs(I can convert them into hexadecimal strings)
• have an efficient way to render them on the screen, with specified color
• have a way to store dialogue data, and render strings of characters

I'm sure I can find a way on my own, but so far I haven't had luck with the rendering part, and I'm also worried that it might be inefficient
