Several ID fields in Setup accepted IDs like ümlaut or abcℕ, although the
rule they advertise is ASCII letters, digits, dash and underscore and the REST
API rejected those IDs. These fields now apply the ASCII rule too, and answer
with:
An identifier must only consist of letters, digits, dash and underscore and it must start with a letter or underscore.
Affected are: * the Unique ID of dynamic host management connections * InfluxDB connections * OAuth2 connections, predefined conditions and passwords * the Site ID under Distributed monitoring * the Unique ID of message broker connections
The stricter check applies to new objects only.
