Glyphs

A style's glyphs property provides a URL template for loading signed-distance-field glyph sets in PBF format.

"glyphs": https://api.nextbillion.io/fonts/{fontstack}/{range}.pbf

This URL template should include two tokens:

  1. {fontstack} When requesting glyphs, this token is replaced with a comma separated list of fonts from a font stack specified in the text-font property of a symbol layer.

  2. {range} When requesting glyphs, this token is replaced with a range of 256 Unicode code points. For example, to load glyphs for the Unicode Basic Latin and Basic Latin-1 Supplement blocks, the range would be 0-255. The actual ranges that are loaded are determined at runtime based on what text needs to be displayed.
