1This file has the relevant components from ICU copied to handle basic 2UTF8/16/32 conversions. Components are copied from utf.h utf8.h utf16.h and 3utf_impl.c 4 5The main change is that U_/U8_/U16_ prefixes have been replaced with 6CBU_/CBU8_/CBU16_ (for "Chrome Base") to avoid confusion with the "real" ICU 7macros should ICU be in use on the system. For the same reason, the functions 8and types have been put in the "base_icu" namespace. 9
