Easier Handling of German Umlauts or other special Characters in the SCP Portal

Hello SAP Portal Community,

when I create a new group in a SAP Cloud Platform Portal Site from Type SAP Fiori Launchpad and use German Umlauts:

The result looks still fine after saving for the first time:

But as soon as I refresh the page the Umlauts look very strange:

But after some try and error I found that the text fields for the Portal follow the standard set by i18n.property fiels and must be ISO-8859-1 encoded. To to that efficiently the tool native2ascii can be used which is part of Java. I've used it on a terminal window:

$ native2ascii 
öäü ÖÄÜ ß
\u00f6\u00e4\u00fc \u00d6\u00c4\u00dc \u00df

Then I've copied the resulting unicode representations into the Group Name:

And the result in the Launchpad looks fine then:

But can't this process be much easier and the Portal Service just takes care of the conversion in the backgroud?

Best regards
Gregor
