I don't know the specific answer, but the definition of a wide character itself is pretty vague. For example ISO10646 (~Unicode) has specification for both 16 and 32 bit characters, both of which would be considered "wide". Unix wide character implementations generally define "wide" as large enough to handle any locale the vendor plans to support, and it may vary from implementation to implementation. For network communications using ISO10646/Unicode, byte encodings such as UTF-7 or UTF-8 make things such as wide-character tcp streams irrelevant, and they head off endian debates in the process. -john
