Why is the last character not copied to the clipboard?

The issue of the last letter of a string not being copied to the clipboard is often related to how the string is being processed or copied. One common reason is that the string might be being truncated or not properly null-terminated when being passed to the clipboard API. Another possibility is that there's an off-by-one error in the code handling the string, causing it to miss the last character. To troubleshoot, check the code that handles the string copying and verify that it correctly includes the entire string.
