These two characters are different: が and が.
The first one is actually two characters. If I try to delete it with backspace, it will first delete the dakuten, leaving behind the か。I need to press backspace again to delete it completely.
The second is just one character and will be deleted by backspacing once.
You can test this yourself by copying and pasting on a text editor.
I would like to transform the first kind of character into the second so a learning app I use can parse it properly. Is there a way to do this?
Note: In this post, the double-character が is rendered as two characters. However, when I type the double-character が, I see it as just one character on my Mac. If in reality, the double-character が is just two characters that are put together by my Mac, then my question still stands. How do I turn these two characters into one?
Note2: I get these characters from copying Japanese from a PDF file.
