The Google Fonts FAQ says to find fonts for your language with the Language filter. Open Google Fonts with the Vietnamese filter, or go to Filters, then Language, and choose Vietnamese.

Type a Vietnamese sentence into the Preview box in the left column, and every font in the list shows that same sentence, so you can compare how each one places the marks.

If you want to use a font outside the filter, type a test sentence with diacritics before you build a whole design around it.

The SIL Open Font License allows commercial use, just not selling the font alone

According to the Google Fonts FAQ, all Google Fonts are open source and free of cost. You can use them commercially, even inside a product that is sold commercially. You can also use them in any logo.

The most common license is the SIL Open Font License. Some fonts use the Apache license or the Ubuntu Font License.

The OFL text lets you use, study, modify and redistribute the fonts freely as long as they are not sold by themselves. Documents you create with the fonts are not bound by the license.

The official OFL site adds that you can use OFL fonts in books, posters, artwork, logos and websites, and no acknowledgement is required.

How can you tell if a font has full Vietnamese diacritics?

The fastest way is to type a test sentence with letters that carry two stacked marks, such as ễ ỡ ặ ậ ổ. Add capitals like Ễ Ộ Ặ to check the marks above uppercase letters.

On Google Fonts, the Glyphs & languages tab for Be Vietnam Pro lays out each letter, including ă ắ ằ ẵ ẳ â ấ ầ. The page shows only a subset of glyphs, so download the font to see the full set.

After you install the font, type the same sentence again in Word or your design app at both large and small sizes. If any mark sits off or overlaps badly, switch fonts before you make a whole batch of images.

Install a font on Windows: right-click the .ttf file and choose Install

Microsoft's Manage fonts in Windows page explains how to add a font from a file:

1. Download the font file and make sure it is a TrueType (.ttf) or OpenType (.otf) file. If it is a .zip file, right-click it and select Extract.
2. Right-click the font file and select Install. To install for every user on the computer, select Install for all users.
3. If Windows asks to allow changes to your computer, select Yes only if you trust the source of the file.
