So, there are three kinds of entities:
- accented Latin letters
- Unicode code points representing them
- Standard TeX/LaTeX commands that represent them.
Of these, Unicode code points are defined best. Everything is in the standard. The two others are more loose:
Which are the Latin letters? Is
Mc a letter? How about
ae? What is considered an accent? There are so many of them.
Which are the "standard" latex/tex commands? Which packages are allowed, and which are not?
There is no definite one answer to these questions. But, I presume there must be tables which carry out some kind of unification of these terms.
This question asks for a more or less "standard" or "community acceptable" table of mappings between instances of these three concepts. If this sounds to philosophical, then read this question as "Standard table of mapping of Unicode and LaTeX accents". One way of searching would be in the
unicode-math package, but there must be more concise maps, presumably used by other the designers of
