This is an artifact of good design on the part of the ISO 2022 crowd
and a little artistry by the font designers.  ncurses can happily
treat EUC as a byte stream because of the GL/GR design; the Japanese
characters don't cause any problems as long as it's 8-bit clean.

ncurses gets the character positioning right by the simple expedient
of making characters with 1-byte codes half as wide as characters with 
2-byte codes, and using a linear unit == 1 halfwidth character width.
