Mono-spaced Fonts

How do you create a mono-spaced font in Glyphs Mini. Does it require using Glyphs?
Will this also provide the ability to assign glyphs to normally invisible characters?
The goal is developing a font for a programmer’s text editor.


You need the full version of Glyphs to export a specifically monospace font. But you make a font with equal glyph width and this should work as expected.
