Access indesign document contains using textrange

Hello

I'm quite sure I'm not the best person to answer this - but I'll give it a go - maybe it can inspire you to find a better solution

// Assuming you have a reference to an InDesign document called myDocument
var myDocument = app.activeDocument;

// Assuming you have a TextFrame or any other text container in the document
var textFrame = myDocument.textFrames[0]; // Replace [0] with the index of your desired text frame

// Get the text contents of the text frame
var text = textFrame.texts.everyItem().getElements();

// Loop through each text object
for (var i = 0; i < text.length; i++) {
    var textRange = text[i].characters.everyItem().getElements(); // Get all characters in the text object
    
    // Loop through each character in the text object
    for (var j = 0; j < textRange.length; j++) {
        // Convert the character to a PMString or WideString
        var character = textRange[j].contents; // This will give you the Unicode value of the character
        
        // You can perform any comparison or manipulation here using the character variable
        // For example, you can compare it with the Unicode value of the paragraph return character
        if (character.charCodeAt(0) === 13) {
            // Do something when the paragraph return character is found
        }
    }
}
