I just tried creating a project in Maven whose artifactId is made up entirely of non-English characters ("日本国").
I get the following feedback from Maven:
ERROR] FATAL ERROR
[INFO] ------------------------------------------------------------------------
[INFO] Error building POM (may not be this project's POM).
Project ID: com.worldevolved:日本国
POM Location: /tmp/日本国910145040748591900/pom.xml
Validation Messages:
[0] 'artifactId' with value '日本国' does not match a valid id pattern.
Is there anything I can do to my POM file to get Maven to read the artifactId as is? Or does Maven not support Unicode characters in the artifactId?

artifactId is the name of the jar without version. If you created it, then you can choose whatever name you want with lowercase letters and no strange symbols. If it's a third party jar, you have to take the name of the jar as it's distributed. eg. maven , commons-math.
groupId – a unique base name of the company or group that created the project. artifactId – a unique name of the project. version – a version of the project.
The main difference between groupId and artifactId in Maven is that the groupId specifies the id of the project group while the artifactId specifies the id of the project.
No it doesn't support. According DefaultModelValidator class 'artifactId' and 'groupId' have to match following regular expression
ID_REGEX = "[A-Za-z0-9_\\-.]+"
If you are intrested in other validations of maven pom file, looking into this class source code will be helpful.
