Groovy script will fail with special characters in object names

[Martin Heini]

We are upgrading to Jira 7.9 and ScriptRunner 5.4.11. After migration some Groovy Scripts failed when including custom fields or issue types names with german 'umlauts' like ä, ö, ü or their capitals.

e.g. actually in a workflow 'Script Validator'

(issue.issueTypeObject.name == '��nderung') ||
 ((issue.issueTypeObject.name == 'New Feature') &&
 (cfValues['R��ckantwort']?.value != 'keine ��nderung'))

Encoding is defined as UTF-8.

In origin environment and earlier stage environment Jira 7.0 and ScriptRunner 5.1.6.2 all these scripts were still correct.:

(issue.issueTypeObject.name == 'Änderung') ||
 ((issue.issueTypeObject.name == 'New Feature') &&
 (cfValues['Rückantwort']?.value != 'keine Änderung'))

Need some help - otherwise I will change all the object names, custom field options and scripts...

Thanks, Martin

We set LANG and LC_ALL already in the SLES base Docker image to en_US.UTF-8; that's all!
