Xojo’s RTF subset: expanded ?

I have in a window, a TextArea where I report tabbed data.

Of course, Xojo \tabs uses the running OS defaults \tab and these does not match my needs.

After some reverse ingineering, I am able to add the tab values I need.

In my debug session I allowed to save TextArea1.StyledText.RTFData, then open it either as rtf code or rendered rtf.

The code is OK and the rendering too.

But: assigning that .StyledText.RTFData to a TextArea does not takes into account my tabs.

Is there’s a solution ?

PS: Microsoft Word nor WordPad are involved here. I just insert my list of tabs into the Xojo generated rtf.

Example of the code header (without actual text):

{\\rtf1\\ansi\\ansicpg1252{\\fonttbl{\\f0\\fnil .AppleSystemUIFont;}}{\\colortbl\\red0\\green0\\blue0;} \\pard \\tx2267\\tx2834\\tx3401\\tx3968\\tx4535\\tx5102\\tx5669\\tx6236\\tx6803\\pardirnatural\\partightenfactor0

Line 2 is the rtf code I added.
