Error while importing certificates

[tkempf]

Hi,
i'm fairly new to truenas and trying to import a CA on truenas12-release without success. I'm always getting some python decoding errors.
The Organization name of the cert contains the Umlauts 'ü', which i suspect is the problem here.
Is this a bug in Truenas ? Does anybody know, if it's possible to import certificates with Umlauts and if so, how to do it?
TIA
Tom


Here is the Public Key of the CA i'm trying to import:
