InDesign Text Modification Script Skips Content

Question

This InDesign Javascript iterates over textStyleRanges and converts text with a few specific appliedFont's and later assigns a new appliedFont:-

var textStyleRanges = [];
for (var j = app.activeDocument.stories.length-1; j >= 0 ; j--)
  for (var k = app.activeDocument.stories.item(j).textStyleRanges.length-1; k >= 0; k--)
    textStyleRanges.push(app.activeDocument.stories.item(j).textStyleRanges.item(k));

for (var i = textStyleRanges.length-1; i >= 0; i--) {
  var myText = textStyleRanges[i];
  var converted = C2Unic(myText.contents, myText.appliedFont.fontFamily);
  if (myText.contents != converted)
    myText.contents = converted;        

  if (myText.appliedFont.fontFamily == 'Chanakya' 
  || myText.appliedFont.fontFamily ==  'DevLys 010' 
  || myText.appliedFont.fontFamily ==  'Walkman-Chanakya-905') {          
    myText.appliedFont = app.fonts.item("Utsaah");
    myText.composer="Adobe World-Ready Paragraph Composer";
  }
}

But there are always some ranges where this doesn't happen. I tried iterating in the forward direction OR in the backward direction OR putting the elements in an array before conversion OR updating the appliedFont in the same iteration OR updating it a different one. Some ranges are still not converted completely.

I am doing this to convert the Devanagari text encoded in glyph based non-Unicode encoding to Unicode. Some of this involves repositioning vowel signs etc and changing the code to work with find/replace mechanism may be possible but is a lot of rework.

What is happening?

This is untested since I'm not able to test against your document, but try using getElements() like below:

var doc = app.activeDocument;
var stories = doc.stories;
var textStyleRanges = stories.everyItem().textStyleRanges.everyItem().getElements();

for (var i = textStyleRanges.length-1; i >= 0; i--) {
  var myText = textStyleRanges[i];
  var converted = C2Unic(myText.contents, myText.appliedFont.fontFamily);
  if (myText.contents != converted)
    myText.contents = converted;        

  if (myText.appliedFont.fontFamily == 'Chanakya' 
  || myText.appliedFont.fontFamily ==  'DevLys 010' 
  || myText.appliedFont.fontFamily ==  'Walkman-Chanakya-905') {          
    myText.appliedFont = app.fonts.item("Utsaah");
    myText.composer="Adobe World-Ready Paragraph Composer";
  }
}
