I have documentation with some mathematics, that I want to convert via LaTeX, but I'd also like to keep it as much readable in source as possible (as it's more for me than anybody else). Since I can write many mathematical symbols directly with digraphs in vim and they show correctly in fonts I use, I would like to use them instead of the TeX commands. There is a package
unicode-math that is supposed to do it, but it would need lualatex and does not work anyway (bug report).
Now I am really using just a handful of symbols. Is it possible, and if it is, how, to map the characters I want to use manually? I have looked at the
inputenc documentation, but couldn't make much sense of it and didn't notice relevant examples. Or, alternatively, can I workaround the bug somehow?
