The whole Debian archive is regularly analysed and a detailed font review is produced:
a report page is generated for each package which contains one or more font files to provide reviewers (yes that could be you!) with image specimens (only covering Latin Unicode blocks for now sorry!); clicking on this specimen will bring you to the report page for that specific font containing other useful information like if it's available in more than one package and also font metadata including detailed licensing and author information, smart font features, along with Unicode coverage by blocks, fontlint reports and other things. You can also look at a very big page with specimens and author links for each font, or the simpler text summary with licensing information. (the report takes a little while to run, so if the page isn't complete yet please come back later).
Please use the information extracted from the various packages in this review to help us fix font-related bugs in Debian: restricted or duplicated fonts in packages, licensing clarifications, advocacy to upstream (resources to make this easier: the bug report template and the community-supported Go for OFL! campaign), etc. Thank you for your contribution!
