29.0.91; Coding system detection defect in html |
|
Date: |

The function `sgml-html-meta-auto-coding-function' signals error for html
file with legacy encoding specification.
0. Save the following file as /tmp/foo.html with the coding system `euc-jp':
----------------------------------------------------------------------
<!DOCTYPE html>
<html lang="ja">
<head>
<meta charset="EUC-JP">
<title>dummy</title>
</head>
<body>
あいうえお
</body></html>
----------------------------------------------------------------------
1. emacs -Q
2. C-x C-f /tmp/foo.html RET
3. M-: (sgml-html-meta-auto-coding-function 1000) RET
4. Then emacs signals error with the following backtrace:
Debugger entered--Lisp error: (coding-system-error iso-2022)
coding-system-plist(iso-2022)
coding-system-equal(utf-8 iso-2022)
sgml-html-meta-auto-coding-function(1000)
eval((sgml-html-meta-auto-coding-function 1000) t)
eval-expression((sgml-html-meta-auto-coding-function 1000) nil nil 127)
funcall-interactively(eval-expression (sgml-html-meta-auto-coding-function
1000) nil nil 127)
call-interactively(eval-expression nil nil)
command-execute(eval-expression)
It seems that this error is due to change in
`sgml-html-meta-auto-coding-function' introduced in emacs 27. When I use
emacs 26.1 definition of the function, it returns `euc-jp' as expected.
