I don’t know where, if at all, this fits into the topic, but just in case…
I have a plugin for rendering text, although I’ve left it hidden (but should be usable) owing to the obviously lacking state of its docs. I keep meaning to set aside some time and flesh them out, but thus far that time hasn’t come. :( The glyphrenderer and FontInfo pages are the most relevant ones. The other pages are fairly low-level and not well-tested; in theory their APIs can be used to build meshes of glyphs, an avenue do I hope to explore, but I should probably just omit them for now.
The plugin is a very thin veneer over the stb_truetype library in stb that seems to be a popular choice for rendering text. The FontInfo:Make*Bitmap*() APIs offer a few ways to do this. They render characters out as blobs of bytes, which my Bytemap plugin was made to address. (The sample shows a use case or two.) In light of Corona’s own recent addition of font metrics APIs I’m not sure how much the remaining FontInfo methods bring to the table… I’ll have to investigate whenever I do finally get back around to this project and decide what to do about them.
EDIT : An example video of the plugin I mentioned, which I’m lately updating, is shown here. (I’ve finally been attending to the docs too.) I might see if I can rename it to truetype as well, so the link above might not be long for this world.
