I would like to make use of the component "TDBAdvRichEditor"
TDBAdvRichEditor persists natively in a binary format, so you'd need to use a binary blob field. If you want to persist in RTF format, use TAdvRichEditor with TDBAdvRichEditorRTFIO for databinding
How can I configurate the charset of my RTF content?
At this moment this is hardcoded to the standard ANSI CP1252
Is there any solution to display my text correct.
I cannot see an issue with these characters.
Do you have more details how to reproduce this?
I use the ADVRichEditor componente with the TDBAdvRichEditorRTFIO for save & load the Binary Blobfield from my Firebird Database. When I use a word like "Grüße". The Component display this text after save & load it from the Database. 'Gr??e'
Are you sure this is a binary blob field? When you use a binary blob field, you don't need RTF btw, you can use TDBAdvRichEditor.
I have especially retested the functionality of TDBAdvRichEditorRTFIO but could not see an issue here. Perhaps you can separately try TAdvRichEditorRTFIO and save & load from file (and test the file with another editor like WordPad). If this works, the issue must be with the DB field.
