Since we don't do any such encoding for C or C++, this is not suitable for 
any case where the identifiers are meant to be link-compatible with C or 
C++ (unless we implement such encoding for C and C++ on target OSes that 
need it, presumably in a way ABI-compatible with how the OSes' own 
compilers handle UCNs in identifiers if they support that feature, of 
course).
