Fonts (glyphs)
The glyphs style attribute provides a URL template for loading an SDF set in PBF format. How to use it is as follows:
"http://***/vt_map/font/{fontstack}/{range}.pbf"
The URL template should contain two tokens:
{fontstack}Whenglyphsis requested, this token will be replaced by a comma-separated list of fonts from the font stack specified in thetext-fontproperty of the symbol layer.{range}When requestingglyphs, this token will be replaced with a range of 256 Unicode code points. For example, to load glyphs forUnicode Basic LatinandBasic Latin-1 Supplement block, the range should be 0-255. The actual range loaded is determined at runtime based on the text that needs to be displayed.
