But in a way that violates the Ada95 standard: The GNAT conversion
routines only work if the Wide_Character encoding used in the
Ada program is also JIS/EUC. The Ada95 standard however requires
that the Wide_Character encoding is the ISO 10646 BMP. Strictly
speeking, the library would have to include the huge Unicode<->JIS
conversion tables on ftp.unicode.org in order to provide a
conforming implementation. UTF-8 instead of EUC and Shift-JIS
is clearly the right encoding to use here.
