Scan Invented Symbols

Hello everyone, I have created a font in which some already existing symbols represent my own symbols (I will leave an image for better understanding). I want to be able to scan my symbols and when they're written in the text box they appear to be the ones that already exist. How can I establish the relationship between the existing ones and my symbols? Thank you all for your help, have a nice day :)!

How are you handling the scan, and thus converting the image to characters?

If this:

image

is a font, can you simply change the font to e.g. Arial to get "standard" letters, then do the mapping ?

I think you invented a good Turing test.

It looks like you are using the Text Recognition extension by @Kumaraswamy ...

Can you provide an example image you are acanning and the scan result?
