These two pieces of texts, they are completely same. Only showed in different font. Set the font to Courier is the trick.
The keyword here is monospace.
I create a long AppleScript to do what you want to do. Due to my English skill, I cannot explain it in detail, but I write a lot of comment in the script. It's not simple and beautiful, but it works in limited condition. You can check if it helps.

Hi, Yu.
Your English is better as mine. And your solution is amazing. It is as exactly as what I needed.
This thought process must have taken a long time.
Many thanks!
