Extend the built-in PHP GD fonts
I like the built-in fonts for GD, they're small, fit tidily in the pixel grid, and come in a range of useful sizes.
But they only support the 32-255 character range.
Is it possible to extend these fonts in any way? For instance, I want to allow Japanese characters. Using fullwidth characters I'd want to produce something like this (from Wikipedia)
Is there any way to extend the built-in font like this? Or alternatively, is there a font available that is the same as the built-in one but with support for more characters? Any TTF font I've tried to use results in antialiasing, which is disastrous on palette-based images...
According to the doc, you can disable antialiasing for TTF fonts by using the negative of a color index for the color parameter of the imagettftext function.
