advance Kerning

I'd just like to note that after a week, many exchanges and this long detour into a scripted solution, I have absolutely no idea what it is the OP wants to accomplish. Just maybe some clarity on the actual task/process would help focus things, here.

Okay, @rehana36276218  so it sounds like you need something a bit customised. I thought this was an interesting tool to have, so I have written a script that may help you. See if you can follow what it does and how, and let me know if it works in your situation. It is quite configurable via the `kerns` array.

/**
 * @file Kern Words.js
 *
 * Finds particular words and sets the kerning of those words explicitly.
 *
 * Tips:
 *   -  Edit the `kerns` array to suit your words and kerning.
 *   -  The `properties` object can contain any valid `findGrepPreferences`
 *      properties and values.
 *
 * Important:
 *   -  The `kerning` values correspond to the words' insertionPoints
 *      so the first kern value is BEFORE the first letter of the word.
 *      for example the word 'cat' will have 4 insertionPoints, and the
 *      kern object might look like this: {word: 'cat', kerning [-5, 6, -30, 8] }

not resolve my issue please someone look on this challenging job

If you set an override or global value for kerning, it will be applied regardless of what the font data specifies for each character. More importantly, it will override the many kerning pairs defined in most fonts, including, most likely, one for the two letters above.

Start by resetting this style, or all styles, to "Metrics" kerning (the default) and removing all overrides you may have applied. That should eliminate all these gaps, which your global setting has created. Also check the other two settings noted, for each affected style, as they can have similar effects:

Hi @rehana36276218, you could try this script by @Peter Kahrel. It applies custom kerning pairs.
