We used 16-bit variables to store the 'character code' everywhere but this won't let us represent anything beyond U+FFFF. This patch changes those variables to a custom type that can be 32 or 16 bits depending on the build, and adjusts numerous internal APIs and datastructures to match. This includes: * utf8decode() and friends * font manipulation, caching, rendering, and generation * on-screen keyboard * FAT filesystem (parsing and generating utf16 LFNs) * WIN32 simulator platform code Note that this patch doesn't _enable_ >16bit unicode support; a followup patch will turn that on for appropriate targets. Appears to work on: * hosted linux, native, linux simulator in both 16/32-bit modes. Needs testing on: * windows and macos simulator (16bit+32bit) Change-Id: Iba111b27d2433019b6bff937cf1ebd2c4353a0e8
