9.9.1.3 Opposite of csname

https://tex.stackexchange.com/landing/r/digest?cta=question&id=673614

If I have a macro \Name that expands to a macro name, I can use that with \csname or the various tools from etoolbox. Can I do the opposite, i.e., get the name of a macro? 
My use case is the following:... 
[macros] [definition] [csname]

9.9.1.4 Fix Kerning Internal to a Unicode Character

https://tex.stackexchange.com/landing/r/digest?cta=question&id=673947

Is there any way to drill down into the code that defines, for example, a'\274\214 to fix the kerning of the diacritics?  It's worse in ebgaramond; it's not very much better in computer modern. 
\documentclass{... 
[greek] [kerning] [ebgaramond] [diacritical-mark]

9.9.1.6 Inconsistent interline spacing in enumitem

https://tex.stackexchange.com/landing/r/digest?cta=question&id=674096

I'm currently working on a set of notes and would like to encircle the item numbers in the enumerate environment. This problem largely seems to have been solved by Raphink in the thread Enumerated ...

I need a macro to create entries (rows) in a table. As proposed here I was successfully using the environ package together with the tabu one. Since tabu is not maintained, I decided to switch to ...
