Masato -

Trouble with the fancy characters is you never know who'll see them, unless someone tells you.

Your first set - 257, 275, 299, 333, 363 all display on my Internet Explorer/WinXP with some language extensions installed.

Your name in Japanese is invisible to me; I don't have Japanese extensions installed.

In the last set, only the 9835 character shows for me.

Windows 95 and 98 do not have Unicode capability, and as far as I have been able to determine, can't be upgraded to it. They can use multiple "pages" of font, but the fonts that came with them are pretty much what's shown by the Character Map utility.

Window 2000 and Windows XP are capable of using full Unicode font sets, but are rarely equipped. The fonts that came with them do have quite a few "International" characters added, but you have to go to extremes to get full Unicode fonts.

What you have on your machine depends on where you bought it, since Windows and all of the Office programs are "localized" for the point of sale. Almost everybody does get the Latin 1 set, but it's a guessing game beyond that.

The "Official" reference is Developing International Software, 2d edition," Microsoft Press (Dr. International Series), 2003, ISBN 0-7356-1583-7. I wouldn't rush out to buy it, as it's a typical Mickey$oft work - although not as bad as some. (They really need some new authors(?).)
