International characters break Communities page

[jesterhodl]

Describe the bug Communities with international characters, like the French, or Polish 21 communities can get messed up. See repro steps.

To Reproduce

1. Go to: https://btcmap.org/communities
2. From the dropdown pick "Dwadzieścia Jeden"
3. The page reloads, everything's fine so far. The address bar shows: https://btcmap.org/communities#Dwadzie%C5%9Bcia%20Jeden
4. So now you think you can go and share the URL. So you go visit it: https://btcmap.org/communities#Dwadzie%C5%9Bcia%20Jeden
5. But it loads with errors:

• The community name is Dwadzie%C5%9Bcia Jeden
• The dropdown is not populated with the value
• The local communities do not display

6. It does fix itself only after you pick the right value from the dropdown

Expected behavior When using a link generated by the btcmap like these:

• https://btcmap.org/communities#Dwadzie%C5%9Bcia%20Jeden
• https://btcmap.org/communities#D%C3%A9couvre%20Bitcoin

The international characters should be handled in such a way that the dropdown detects them and page loads correctly.

Screenshots Dropdown is OK after first visit:

But when you use visit the generated link it will mess up the name and won't load the communities:

Additional context None
