// This is quite inefficient. See the GSUText stuff for how
// to use ICU 4.6 UText objects as NSStrings. This saves us from
// needing to do a load of O(n) things. In 4.6, these APIs in ICU
// haven't been updated to use UText (so we have to use the UChar buffer
// approach), but they probably will be in the future. We should
// revisit this code when they have been.

// The only unsigned case we actually need to worry about is unsigned
// long long - all of the others are stored as signed values. We're now
// falling through to the double case for this, which will lose us some
// precision, but hopefully not matter too much...
