Add country flags to language select

[jguthrie100]

I thought it might be nice to include country flags within the language select dropdown..

1. How do we deal with languages that are used in multiple countries?
2. Can we use Unicode symbols instead of including another library?

[jguthrie100]

Sure, I can change it to use emojis/unicode.

For multiple countries, I just used the main country (apart from English, where I used the UK, but could make it USA)

I was thinking of even listing multiple flags for certain languages, but it might look a bit cluttered!

[tananaev]

Yeah, let's do emojis and set the English to the USA flag as the more common.

Apparently Windows doesn't have support for flag emojis? I don't have windows so I can't check..

It's not working on windows even with a custom font, like roboto?

[jguthrie100]

My understanding that Microsoft have left all unicode flags out of Windows in order to avoid issues around supporting various countries (i.e. whether to include Palestine/Israel flags etc)

[tananaev]

Can you update the pr and I'll try.

[jguthrie100]

Have you tested it on Windows? I just heard back from someone that it only shows the unicode letters..

Doesn't work on Windows, but I've added this check: https://github.com/traccar/traccar-web/commit/c36d1bed4a8781b2307fe2bfcdd1c6d4ddd00d64.

Is it not worth just including the tiny library so the majority Windows users can see flags too?

[tananaev]

OK, let's do it.
