Can you please clarify a little what is AGL and what rules it uses to find suitable Unicode characters?

I would appreciate anyone for detailed explanation of this AGL rules. What is it, how it works, etc.

Does anyone has knowledge about that?

Noone says you need to hard code a table. You could load it as a data file and then use it from your code.

Yeah, its not the big deal how to create this data.

I am worried about what to do, if I cannot find some symbols from user input inside this table because there will be no corresponding mapping between Unicode and AFII for example.

Thats the case, which I want understand how to handle correctly.

You could try to fall back to other fonts and if those also do not have the character you display the missing-character-square (and if you want display the hex code inside that, like browsers do).

@wintertime

You didn't answer my question.

My question was: How to match user input from keyboard (which will be definitely in Unicode) to the character inside font in case when some characters could be defined in AFII (not in Unicode).

For example, user press “A” button and I want to find this character in the font. This char definitely present there, but in AFII, which does not match to Unicode.

So, how to find this char in the font if it will be missing in the hardcoded data dictionary, but present in the font itself?

For that, you probably have to read the documentation for that table and/or file format yourself. I doubt anyone here would know that without doing the same.
