DT Phudu is a display sans-serif typeface inspired by Vietnamese hand-lettering billboards in the old days, that supports up to 192 languages and has special diacritical marks. It focuses on readability on large scales and is easy to assess. DT Phudu now consists of 5 weights from Light to Black, and the lighter it gets, the extended it becomes, for people to read it easier compared to other lightweight narrow typefaces. Some details are cutting-edge and not sharp for this purpose too.
In the progress of learning and crafting types, I have always thought about what makes a Vietnamese typeface. If we rewind to the past, we can see our lettering styles on the billboard stores, when the artists adapted Latin typefaces and then added marks based on their styles. Among those, there were mostly all-caps sans-serif types played as descriptions or sometimes the store's names themself. To make a new easy to read and easy-to-get typeface, I mixed some of the research from the story above with letters. I don't want to just revive the types, I want to improve them, so they can fit the modern-day styles but still have "Vietnamese" souls in them. The typeface was named DT Phudu (phục dựng) - "revival" in Vietnamese, and has a meaning of timeless (quite the opposite of the name when it can be read as "phù du" - ephemeral).
