|License File: NOT_SHIPPED
|This file has the relevant components from ICU copied to handle basic
|UTF8/16/32 conversions. Components are copied from utf.h utf8.h utf16.h and
|The same module appears in third_party/icu, so we don't repeat the license
|The main change is that U_/U8_/U16_ prefixes have been replaced with
|CBU_/CBU8_/CBU16_ (for "Chrome Base") to avoid confusion with the "real" ICU
|macros should ICU be in use on the system. For the same reason, the functions
|and types have been put in the "base_icu" namespace.
