+Subject: [PATCH] Disable broken KEYBD trap for multibyte characters
+
+In UTF-8 locales, ksh breaks when a KEYBD trap is active, even a
+dummy no-op one like 'trap : KEYBD'. Entering multi-byte characters
+fails (the input is interrupted and a new prompt is displayed) and
+pasting content with multi-byte characters produces corrupted
+results.
+
+The cause is that the KEYBD trap code is not multibyte-ready.
+Unfortunately nobody yet understands the edit.c code well enough
+to implement a proper fix. Pending that, this commit implements
+a workaround that at least avoids breaking the shell.
+
+src/cmd/ksh93/edit/edit.c: ed_getchar():
+- When a multi-byte locale is active, do not trigger the the KEYBD
+  trap except for ASCII characters (1-127).

+Subject: [PATCH] Fix long multibyte characters paste issue via ssh (#840)
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+When I paste long multibyte characters(over 80 byte) to ksh via
+SSH, the characters are not displayed correctly. For example, the
+following input demonstrates the issue. ja_JP.UTF-8 encoding is
+used.
+
+Expected command line display:
+$ echo "長い文字列を入れるとkshで文字列が乱れる場合があるようです"
+
+Actual command line display:
+$ です"echo "長い文字列を入れるとkshで文字列が乱れる場合がある
+...with the cursor over the 'e' in 'echo'.
+
+This issue appears to be caused by the ed_read() function splitting
+a multibyte character sequence when reading into an 80-byte buffer.
+This leads to incorrect character interpretation and display.
+
+Therefore, we edited the code to handle the case where the buffer
+size is full in the middle of a multi-byte character.
+
+src/cmd/ksh93/sh/edit.c:
+- putstack():
+  - Before retrying to interpret a multibyte character in case of a
+    split due to end of buffer, restore the start position 'p'.
+  - Fix zeroing out errno = EILSEQ.
+- ed_getchar(): Avoid a potential buffer overflow in 'readin';
+  allow for an extra multibyte character, not merely an extra byte.
