Add additional space to string at every existing space

Hmm, this is seemingly exactly what I want, however, doesn't seem to be working for me. Did this actually work for you? Something that's interesting is I copy/pasted the below code from my file, and the number of spaces between the " " pasted as only one, despite in the code having several. Curious..

var myText = doc.activeLayer.textItem
myText = myText.contents.replace(/ /g," ");

How can it be done with an action.  Actions can not use logic to retrieve text layers and search for spaces and insert additional spaces.  And if  you double the amount of spaces how would an action known if the revised text will fit on canvas.  How would an action know how many text layer there are  or where in the layer stack text layers are.  A Photoshop script may be able to do what they want to do. It would not be easy to program such a Photoshop script. If it is not something  they would use all the time they would save time manually editing their text layers.
