Hey Guys,
I am starting my first campaign on Mobile in the next two days. The campaign is a mobile install offer in India. We checked our lander (which is in hindi type) on browser stack and found that a couple phone don't show the hindi font correctly. The following phones either don't show the font at all (blank) or show it with random circle dot characters that aren't hindi. Is there a font that anyone can recommend that is universal for all browsers / phones that is hindi? 
- Sony Xperia
- Droid Razr
- Galaxy SII
Appreciate the help guys!
I know it's not ideal, but if you can't come up with a solution you can make it a picture.
No idea to be honest, but I imagine it has to do with the font you use and/or the page encoding (e.g. UTF-8).
With different languages, sometimes different encodings are needed - I remember Turkish went weird for me when using UTF-8 (you can set encoding in the page header - http://www.w3schools.com/tags/att_meta_charset.asp).
It may pay to do some research and find out what the native fonts for Hindi are on Android and iOS.
You can then make your page use those fonts, which you can be confident are available on the phone. Otherwise there may be a Hindi webfont out there in the Google font repository or through Typekit.
Failing that, as metalshark suggested, you could make the text a PNG image and avoid the issue entirely.
I looked into this a little while ago, and couldn't find a font that was universal for all phones displaying Hindi.
Can you simply exclude those phones? That's probably the easiest solution.
