tty/teken: fix UTF8 sequence validation logic2023-10-13T05:14:36ZBojan Novkovićbojan.novkovic@fer.hr2023-10-13T05:14:36Zurn:sha1:2fed1c579c52d63b72fc08ffcc652ba0183f9254
This patch fixes UTF-8 sequence validation logic in
teken_utf8_bytes_to_codepoint() and fixes fallback behaviour in
ttydisc_rubchar() when an invalid UTF8 sequence is encountered. The code
previously used __bitcount() to extract sequence length information from
the leading byte. However, this assumption breaks for certain code
points that have additional bits set in the first half of the leading
byte (e.g. Cyrillic characters). This lead to incorrect behaviour when
deleting those characters using backspaces. The code now checks the
number of consecutive set bits in the leading byte starting from the
MSB, as per RFC 3629.

teken: use __bitcount() instead of bitcount()2023-10-07T21:36:59ZChristos Margiolischristos@FreeBSD.org2023-10-07T21:36:59Zurn:sha1:6d3296f16a06bcaa49918799e683936711dcf9c9
The use of bitcount() triggered a build error because it couldn't be
located. __bitcount() on the other hand is defined in sys/types.h, which
is included in teken/teken.h.

tty: fix improper backspace behaviour for UTF8 characters when in canonical mode2023-10-07T18:00:11ZBojan Novkovićbojan.novkovic@fer.hr2023-10-07T18:00:11Zurn:sha1:9e589b0938579f3f4d89fa5c051f845bf754184d
This patch adds additional logic in ttydisc_rubchar() to properly handle
backspace behaviour for UTF-8 characters.
Currently, typing in a backspace after a UTF8 character will delete only
one byte from the byte sequence, leaving garbled output in the tty's
output queue. With this change all of the character's bytes are deleted.
This change is only active when the IUTF8 flag is set (see
19054eb6053189144aa962b2ecc1bf5087758a3e "(s)tty: add support for IUTF8
input flag")
The code uses the teken_wcwidth() function to properly handle character
column widths for different code points, and adds the
teken_utf8_bytes_to_codepoint() function that converts a UTF-8 byte
sequence to a codepoint, as specified in RFC3629.
