Description
ed_quoted_insert doesn't seem to work properly with some of keys.
("properly" means "different from same as readline 8.1")
Steps to Reproduce
Environment:
irb(main):001:0> irb_info
=>
Ruby version: 2.7.4
IRB version: irb 1.3.7 (2021-08-12)
InputMethod: ReidlineInputMethod with Reline 0.2.7
RUBY_PLATFORM: amd64-freebsd13
LANG env: ja_JP.UTF-8
- no .irbrc, no .inputrc
- PuTTYrv 0.76-ranvis2 (CJK)
- Keyboard: US
Scenario:
Start irb --readline and type ", ", C-b.
The cursor is at the second ".
% irb --readline
irb(main):001:0" ""
_
Type C-v, C-a, Enter.
% irb --readline
irb(main):001:0> "^A"
=> "\u0001"
irb(main):002:0>
Do the same key operation on irb without --readline.
% irb
irb(main):001:0> "^A"
=> "\u0001"
irb(main):002:0>
Compare the input string "^A" and the output string "\u0001" with irb --readline.
Result:
