This is the first attempt at fixing problems with location search when Chinese or other similar languages are used. Please see commit messages for details.

Tested manually on both Firefox and Brave. It looks like the used select component has more strange issues. Was not able to fix those but also checked that I didn't create more issues. The react-select version is quite old: ^1.0.0-rc.5 in package.json while latest release is 5.7.3.

@willemarcel Could I request your review on this?

GitHub doesn't allow me to add any reviewers to this PR. I hope you forgive this ping after weeks of waiting and not understanding how to better request a review from someone in this project.

@lliehu sorry for the delay and thanks for the PR. I'll review it this week.
