What I'm trying to do is to translate an application interface language from Korean to English

I've added a new section using CFF Explorer because the application doesn't have a size to extend the translated text

Then I used Ghidra to change the address for the text to the new address location

The problem I've faced is that the new text is cropped at specific character eg. The original text USB를 읽고 있습니다. and the new text Reading The USB the problem is the new text appears like this Reading The US without the last character, and this problem appears in different places I've tried to change the text with the same approach, I know that this problem is related to the text size but I can't find where I can change the text size

here is a sample of code taken from IDA
