I have encountered inconsistent paste behaviors in UITextView depending on whether the text is in English or Korean. When pasting at the beginning of a text with an English sentence in UITextView, a space is added after the pasted text. In the middle, spaces are added before and after the pasted text. However, when pasting at the end, only a space is added before the pasted text. On the other hand, when there is a Korean sentence in UITextView, pasting at the beginning results in the inclusion of "\n" at the beginning of the pasted text, while in other cases, no additional text is added upon pasting. I'm curious to know if this behavior is intentional. I would appreciate understanding the rationale behind appending "\n" in Korean text and the absence of additional text in other cases.
