Display of standardised name in CovPass Check App

[MikeMcC399]

A discussion started in corona-warn-app/cwa-wishlist#573 which leads to the question about whether CovPass Check App displays the standardized name from an EU digital COVID Health Certificate.

For example from the Greek test certificates in
https://github.com/eu-digital-green-certificates/dgc-testdata/tree/main/GR

https://github.com/eu-digital-green-certificates/dgc-testdata/blob/main/GR/2DCode/raw/1.json shows

    "nam": {
        "fn": "ΜΕΝΕΞΕΣ",
        "fnt": "MENEXES",
        "gn": "ΜΑΡΙΟΣ",
        "gnt": "MARIOS"
    }

Would the CovPass Check App show
ΜΑΡΙΟΣ ΜΕΝΕΞΕΣ
or
MARIOS MENEXES
or both?

I couldn't try this out because unfortunately the QR code https://github.com/eu-digital-green-certificates/dgc-testdata/blob/main/GR/2DCode/png/1.png gives a signature error.

For any check of the certificate against passport data, would it be necessary to have the standardized name MARIOS MENEXES showing in the CovPass Check App, which would presumably be the name in the Machine Readable Zone of the example person's passport or would the person performing the check have to compare the Greek name ΜΑΡΙΟΣ ΜΕΝΕΞΕΣ instead?

Thanks for any insight in how interoperability is expected to work in an international environment using character sets not found in Germany!

I missed that this topic is already discussed in #6.
