To map Use Roboto Slab on rm-fonts as roman, Roboto as sans and Robonto (Roboto Mono as, well, mono. Also provide normal and condensed) on ss-fontssans.

The Download the Roboto fonts are installed at your System from Google’s Github projects ([https://github.com/google/roboto/releases|Roboto Sans and also recognized by ConTeXtMono], [https://github.com/googlefonts/robotoslab/tree/master/fonts/static|Roboto Slab]), from [https://fonts.google.com/?query=Roboto|Google Fonts] or several other font pages. If

mtxrun Put the font files e.g. in <tt>texmf--script fonts --list --all --pattern=/fonts/truetype/google/roboto*</tt> and reload the font database:

For this example you can use any Unicode font you likettf robotothinitalic roboto robotothinitalic Roboto-ThinItalic. If you use different fonts do not forget ttf  Now we need to exchange the font names in the example script belowwrite a typescript...(TODO)

At this moment ConTeXt only offers two different font weights inside a typescript definition - roboto Roboto offers six different font weights. A typescript definiton definition also does not does’t know font variants and roboto sans Roboto Sans offers two (normal and condensed).

== Script Solution ==

Solution: you You need to pair the specific weight and variants you need want in your document.
