0.48.0 does not allow nordic chars åäöåæø in package-names

[olekvernberg]

When upgrading from 0.47.1 to 0.48.0, ktlint complains on package names containing åæø.

Observed Behavior

Package name contains a disallowed character (cannot be auto-corrected) (package-name)

Steps to Reproduce

Create class Bar in package with name føø and run mvn antrun:run@ktlint

Your Environment

• Version of ktlint used: 0.48.0
• Relevant parts of the .editorconfig settings

Similar to #1530

More problems like this are likely to occur in this release. 0.48.0 contains some rules which formerly where experimental but now have been added to the standard rules. Also new experimental naming rules have been added in 0.48.x. Can you please run ktlint with --experimental once to identify which of the newly added experimental rules also break on nordic characters?

[olekvernberg]

It seems like it also fails on property-, class- and function-names containing nordic characters when running with experimental rules:

Property name should start with a lowercase letter and use camel case (cannot be auto-corrected) (experimental:property-naming)" on properties containing nordic characters.
Class or object name should start with an uppercase letter and use camel case (cannot be auto-corrected) (experimental:class-naming)
Function name should start with a lowercase letter (except factory methods) and use camel case (cannot be auto-corrected) (experimental:function-naming)

Indeed, that is not entirely unexpected. Thnx for confirming though. Sorry for the inconvenience.
