FEATURE: Capitalize the first letter of all languages

[ghost]

For example, catalan is lowercase, and I need all uppercase native names

Hi @hugovidafe , are you a catalan native speaker? if so, feel free to make a PR.

From my perspective, I can't tell whether those native names are uppercase or not. Some of them don't even have a uppercase, such as "অসমীয়া", "日本語", "中文".

For catalan, is better uppercased

[ghost]

And all native names that start with a letter of the Latin alphabet can start with the first letter in uppercase

v2.1.2 released

Not only Catalan, it was an example...

Opened #32, not sure why not all latin alphabet names have a capital first letter? Used in a list by themselves almost all probably should be.. maybe not as often if used in sentences.
