I'm not terribly surprised. How much use for i18n is there in the typical
embedded microcontroller? We're probably the first project to really use this
code in anger(*); cf. also how we still shake out the odd longstanding
floating point bug in newlib, another area that is significantly less-used in
tiny embedded apps than on desktop workstations.
cheers,

After having sent my mail I started to wonder as well. Unicode and
wide-char support in a 64K RAM board sounds like waste. I had expected
that RTEMS is using this a bit more, though.

plus the entirely missing area of long double support.
