In the past few months, I have been fortunate to play a role in advising Vietnamese diacritical marks for a handful of typefaces. I just updated the advising page with a list of clients. Some typeface are commissioned; therefore, I could not show them. The two recent ones I am excited about are Fragen and Recursive Mono. The Recursive family is still in beta. I can’t wait to see the sans version supports Vietnamese.
On a related note, the traffic for Vietnamese Typography is decent. I don’t use Google Analytics tracking anymore, but Cloudflare keeps track of some analytics. In the past 30 days, there are 16,493 unique visitors, 241,918 total requests, and 12 GB total data served. The last one is a bit of a concern because I use so many typefaces on the site. The recommendation page alone has over 20 typefaces with Vietnamese subsets. Hopefully my hosting provider won’t shut down my sites.
