Where does iconv, and terminal display of stdio, get locale in linux?

Where does iconv, and terminal display of stdio, get locale in linux?
Where is the locale's "codepage" stored? I know the kernel may have one of ISO, C99, or Unicode somewhere in there yet not sure if these have reference when using iconv in termux. I suspect the in kernel codepage has bearing on terminal stdio display; is anybody sure on this? On android it may be hard to find the in kernel locale without a kernel config file.
iconv -l displays a long list of many locales to begin sorting this out where are the codepages of iconv -l stored?

Locales are a mechanism of the GNU C Standard Library implementation (Glibc).
They are not implemented in Android's Libbionic C Standard Library.

As such Termux cannot make use of locales.

@TomJo2000 I gather glibc for iconv and bionicC for stdio. Appreciated.

[TomJo2000]

Unfortunately no.
Android just fundamentally does not use the Locales mechanism.

Unfortunately no. Android just fundamentally does not use the Locales mechanism.

In this discussion the locale is an implimentation of the codepage or whatever you want to call the Unicode android and iconv use. What do you call the glyph bytecode map?

[freedom-foundation]

@TomJo2000 even google does call UTF-8 a locale on top of C/POSIX. Hey, do you know how to find out what revision of unicode my bionic is using? That is what I need to get the "codepage" or bytecode to glyph map.

And this magically solves your problem how exactly?
