The Problem

There is a need to use different characters in the name of the regions.

A Solution

Request to expand the pattern to any characters (Ideally with space support)

Alternatives

Anything Else?

WorldGuard does not have region names, it has unique identifiers for each region. These should not be used as "names". If you have a plugin that is incorrectly using this as a name, it should instead be adding a "display name" flag or similar that is handled in the way you're describing

I am using PlaceholderAPI (https://api.extendedclip.com/expansions/worldguard/)
This assumes that placeholders like %worldguard_region_name% have the wrong name :( (Expected placeholder name: worldguard_region_id)

But I understand that in general this is no longer for you :)

Maybe you can tell them to create a custom flag for placeholder-name, which should be used instead.

That way there would be utf8 support and no issues with mutliple regions in the same spot.
