Can't create or use Japanese fonts at all. PDE - Create fonts -
MS-Gothic/UIGothic etc - include all chars - gives java errors (memory leaks?):

Alternatively, PFont f = createFont("MS-Gothic", 24); etc shows nothing on

Any workaround???

Smaller fonts (24pt) seems OK; 48pt NG.

See bug #98.

In the meantime, use the createFont() method, and pass in a char[] array of
characters you want to use, rather than trying to convert the tens of
thousands of characters in a full unicode font.

Changing this to an enhancement request.
Additional Comment #3 From fry 2010-02-16 11:07
For future releases, the createFont() method will only load characters as
they are used, which should greatly improve the font situation on non-Roman
systems like Japanese. Or with the Create Font tool, you can also specify
what unicode character blocks you'd like to use, making a much smaller font.
