// Demonstrates how U+30FC is sometimes handled as a single-width character
|
||
// when it should be handled as a double-width character.
|
||
//
|
||
// It only runs on computers where 932 is a valid code page. Set the system
|
||
// local to "Japanese (Japan)" to ensure this.
|

//
|

// The problem seems to happen when U+30FC is printed in a console using the
|
||
// Lucida Console font, and only when that font is at certain sizes.
