Diacritics in city names

[StefanBrand]

In an ideal world we could write "Orléans" (with "é") in the angels.json and the resulting mailto: would be orleans@....

This could be handled via Javascript: https://stackoverflow.com/a/863865/9778755

Since the plain text json is the only public list of heavens at the moment (map doesn't work with JS turned off), I would advice against this enhancement at the moment. Whenever there is a public list of heavens that removes non-ASCII characters in the corresponding e-mail addresses, we can go forward with this.

Maybe a "display name" and a "mailto-name" should be available in the source and being processed by fprsmap.
This would not only help for "diacritics", but also for city names with spaces in the name!

@ff2u your suggestion is less magical than mine. It makes the different types of names explicit. I support your suggestion.
