Problems with FlexForms - Soft-Hyphen placeholder char ↵ doesn't get replaced with ­

[X-Tender]

I've spotted it in various situations.
Situation 1: CEs which are created via the Flux, simple inputs and RTEs the ↵ doesn't get replaced with ­
Situation2: A models TCA which gets extended via

$GLOBALS['TCA']['tx_MyExtension_domain_model_event']['columns']['attributes']['config'] = [
    'type' => 'flex',
    'ds' => [
        'default' => 'FILE:EXT:MxExtension/Configuration/FlexForms/event.xml',
    ],
];

Situation3: When I add a FlexForm to a plugin via

$GLOBALS['TCA']['tt_content']['types']['list']['subtypes_addlist']['myExtension_myPlugin'] = 'pi_flexform';
\TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addPiFlexFormValue(
  myExtension_myPlugin',
  'FILE:myExtension/Configuration/FlexForms/aFLexFormForMyPlugin.xml'
);

then the ↵ doesn't get inserted in a RTE textfield when I click the "Insert Soft Hyphen" (normal inputs are working). Also the replacement of the ↵ doesn't work.

Hi X-Tender,
thanks for your feedback. I have fixed the first problem you described and I'm going to check the other two situations later, too.
