Thanks for reaching out, justinandapple.
It sounds like you're trying to copy text from a photo, but when you select text in Latin, it is being corrected to English. We can help.
So based on your description, you're following steps from Interact with text in a picture in Safari on Mac, and using the Copy method to paste the content in a different source.
For the auto-correction behavior you're experiencing, let's see if this helps: Set up auto-correction and add words to your spelling dictionary in Pages, Numbers, and Keynote. Head into System Preferences on your Mac, Keyboard > Text and see if auto-correction is enabled. Also, we've quoted an important section below from this same article, that seems relevant to your request too:
Auto-correction is available for languages that your Mac is set up to spell check. To see these languages, go to System Preferences > Keyboard > Text and click the Spelling pop-up menu. Click "Set Up" to learn how to add spelling dictionaries for additional languages."
Try that out and let us know if things improve.
Take care!
