Americana Fonts

The Americana fontstack is built from Google Fonts. The name "fontstack66" is a nod to Historic Route 66.

Usage

glyphs: "https://font.americanamap.org/{fontstack}/{range}.pbf"

Then, in a maplibre-gl stylesheet, you can use the packaged fonts like such:

"text-font": ["Americana-Bold"]

In order to add fontstack support, modify the fonts.json file as follows:

Add font-family and variant information to the font-families section. The font-family is the name of the font as listed on Google Fonts, e.g. "Noto Sans". Use gfi download "<name of font>" to get a full list of the variants. The variant is everything to the right of the dash in the filename, so if a file is named NotoSans-700.ttf, the variant is 700, though it will be listed in Google as something like "Bold 700". The gfi command requires you to install the google-font-installer package into npm with npm install -g google-font-installer.
Define the range of characters that you want rendered in this font in the glyph-ranges section. Since this is JSON, you'll have to convert hex to decimal here. The named parameter is simply a name that is used in the rest of the file to refer to this range of characters. This is an inclusive range so for example [0, 255] will include codepoint 0 and codepoint 255.
The custom-font-stacks section lists each font-stack and which font/glyph range combinations should be included in that fontstack.
The bundle-font-stacks section lists all font stacks which should be bundled in their original form.

The following fonts are provided:
