Hi! I'm a creator who uses Be Vietnam Pro as a body font. I really enjoy having almost universal diacritic support since having accessible translations is very important to me.
I have been making do with modifying the glyphs themselves on Illustrator to get carons on vowels (◌̌, as in ǎ, ǐ, and ǔ). Hačeks (carons on c and s) are already available, and so is ě. I understand that Vietnamese does not have use carons on vowels, but I think this would be a really great addition to the font.
Thank you so much for creating BVP! It's a fantastic font!
