Adding missing unicode glyphs?

[TheMasterGabriel]

Hi,

Because Minecraft doesn't support all possible Unicode characters, I was wondering if there was a way to add glyphs for the ones it's missing? My first thought was that this would be as simple as adding localized names for blocks/items/entities/etc but looking at FontRenderer, that doesn't seem to be the case.

The vanilla FontRenderer supports 256 pages of 256 characters, which is the entirety of the Basic Multilingual Plane (BMP) and the full value range of a char.

 

To support the full range of Unicode code points, you'll need to iterate through the code points of a String (represented as ints or pairs of chars) rather than the code units (represented as chars). In Java 8, CharSequence#codePoints returns an IntStream of a CharSequence's code points.

 

You'll need to create your own page textures and glyph width file for code points outside of the BMP and arrays to store the page locations and glyph widths. You'll then need to override FontRenderer#renderUnicodeChar to do the same thing as the super method but use your page textures/glyph widths. You can then replace Minecraft#fontRenderer with an instance of your class.
