From 5298d4bfe80f6ae6ae2777bcd1357b0022d98573 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 18 Jan 2022 07:56:14 +0100 Subject: unicode: clean up the Kconfig symbol confusion Turn the CONFIG_UNICODE symbol into a tristate that generates some always built in code and remove the confusing CONFIG_UNICODE_UTF8_DATA symbol. Note that a lot of the IS_ENABLED() checks could be turned from cpp statements into normal ifs, but this change is intended to be fairly mechanic, so that should be cleaned up later.
