Maldivian uses a Thaana script, which is not very widely supported in fonts. There are two main strategies: specify a font-family rule, which lists fonts that are known to contain Thaana letters, hoping that the user has at least one of them, or use a downloadable font with @font-family . In this case, the latter sounds more realistic. To do this, you will need a font that you can legally use in this way.
Free fonts that support Thaana include MPH 2B Damase and TITUS Cyberbit Basic.

I would be very surprised to see an automatic translator for a small language such as Maldivian, and I would also be surprised to see an automatic translator that gives decent results when translating a website.
