[Noteepad++ Questions / Suggestions] - Copying Special characters.

Description of the Issue

I think this can be considered a problem, the Notepad is partly a hex editor, but it cannot copy the special character "NUL", after copying and pasting it turns into a Space. (((((At which the hex from "00" changes to "20", that is, it really goes into a space) Sometimes when editing files, it interferes, for example, when searching for a line in the cache or dll.

Steps to Reproduce the Issue

1.Open any file with special characters.
2. Copy the line in which there is "NUL".
3. Paste the copied line. (After which "NUL" will be replaced by a Space)

Expected Behavior

The question is rhetorical, but I will fill it out according to the template. I expected that "NUL" would remain in place of "NUL" after copying. =)

Actual Behavior

Already described above.

Start by reproducing the reported behavior in Notepad++: open a file containing NUL, copy the line, and paste it. Trace the copy-and-paste path and verify completion by confirming that the NUL remains unchanged rather than becoming a space (hex 00 to 20), with coverage for this case if the project’s existing tests support it.
