utf8data.h_shipped has a large database table which is an auto-generated
decodification trie for the unicode normalization functions and it is not
necessary to carry this large table in the kernel.
Goal is to make UTF-8 encoding loadable by converting it into a module
and adding a unicode subsystem layer between the filesystems and the
utf8 module.
This layer will load the module whenever any filesystem that
needs unicode is mounted.
utf8-core will be converted into this layer file in the future patches,
hence rename the function names from utf8 to unicode which will denote the
functions as the unicode subsystem layer functions and this will also be
the first step towards the transformation of utf8-core file into the
unicode subsystem layer file.

This didn't really answer my questions about the reason for this renaming.
Aren't the functions like unicode_casefold() still tied to UTF-8 (as opposed to
e.g. supporting both UTF-8 and UTF-16)? Is that something you're trying to
change?


Currently, layer's functions are still tied to UTF-8 encoding only. But in future if we will have UTF-16 support then layer file would have to be changed accordingly to support both.
Unicode subsystem layer is a generic layer which connects the filesystems and UTF8 module ( and/or UTF16 in future )
