Best Content Language for Website
Most websites have content written in languages using Latin script. Vietnamese, most European and African languages use Latin alphabets.
Latin fonts have relatively small number of characters than fonts of other scripts - such as Chinese language which has thousands of glyphs.
Most websites are written in English which is a Latin script, also popularly called Roman script.
Generally, a Latin font style subset have around hundred glyphs in total, even if most unique characters are also included in the subset. In other words, file size of fonts with Latin subset is inherently reduced.
It means that if your website is in English, browsers will require relatively small number of glyphs to display text on your web page, unless translation preferred by the end user.
Where English is not a primary language such as India and Pakistan, people prefer to use English language for searching something on search engines including Google and Bing. This is the reason that most Indian websites are also in English. Although India represents almost 18% of the world's population but Hindi is used for only 1% of websites. Similarly, China represents around 20% people on earth but the share of Chinese as website content language is also around 1%. It means that if our website is in English language then it can capture the attention of large audience.
Latin fonts are light weight which load on a fly.
