Jython doesn't support lone surrogates at all. According to https://bugs.jython.org/issue2048 that is by design.
Another place where Jython hits this is in https://github.com/protocolbuffers/protobuf/blob/master/python/google/protobuf/json_format.py#L82
r'[\ud800-\udbff](?![\udc00-\udfff])|(?<![\ud800-\udbff])[\udc00-\udfff]'
Closing since I don't believe we actively support Jython. We're happy to accept PRs for a contributed fix though.
@AdamElliott-AB @rasantel hi guys, have you found a way to slove this?
Not I. I ended up reworking my architecture so Jython wasn't needed. This issue made it too much of a hassle for me.
