texte dans le désordre

What options do you have set in the drop down menu at the top right of the paragraph panel and character panel?

For normal typing, 
In the Paragraph panel, set 'World ready layout' and 'Default Feaatures'
In the Character Panel, set 'Middle Eastern features > LTR Arabic' and set 'Middle Eastern Features > Default Direction' 

Restart Photoshop after setting them

@MICHEL35979092q6ke I cannot replicate the issue you described, can you post a screenshot of the Photoshop interface with all the pertinent panels opened to highlight the issue, also what exact version of Photoshop are you using
