Subject: kate: A NUL byte in not an invalid utf8 character.
Package: kate
Version: 4:18.04.0-1
Severity: normal
Dear Maintainer,
While trying to edit a file I got a "opened with UTF-8 encoding but
contained invalid characters." error.
There was no indication of which or where in the file were this invalid
characters.
Filtering the file with:
iconv -c -t utf8 testfile.txt >testfile.txt.new
Made no modifications to the file (all characters were accepted).
Then I tested the file with:
isutf8 -v testfile.txt
Which also reported no error.
Then I used:
grep -axv '.*' testfile.txt
Which also found no error.
The only solution was to open the file in kate, force editing and force to
write a new file.
The difference bettween both files revealed that the removed characters
were NULs.
That is bytes wit value of zero: 0x00 a.k.a \0
You can reproduce by creating a file in the command line with:
printf 'A good line\nA line with a NUL\x00\n' >testfile.txt
Then, try to edit with kate.
A zero byte is a valid UTF-8 character as reported by the command:
$ unicode -x 0
U+0000 <control>
UTF-8: 00 UTF-16BE: 0000 Decimal: � Octal: \00
Category: Cc (Other, Control)
Unicode block: 0000..007F; Basic Latin
Bidi: BN (Boundary Neutral)
It can be tested with some other tools also.
Please:
1.- Provide a way to "see" or list the characters reported as wrong by
kate
2.- Do not include a NUL as invalid utf8.

I difensori della morale tradizionale sono raramente persone di cuore. Si è
tentati di pensare che essi si servano della morale come di legittimo sfogo
al loro desiderio di fare del male agli altri.
