\MakeShortVerb{\§} 和 \usepackage[utf8]{inputenc}

Question

我有一本十多年前出版的書。它的序言中包含以下程式碼：

\documentclass{article}

\usepackage[cp1251]{inputenc}
\usepackage[T1,T2A]{fontenc}
\usepackage[english,russian]{babel}

\usepackage{shortvrb}
\MakeShortVerb{\§}

\begin{document}
§\begin{i}§
\end{document} 

現在我想將原始檔轉換為unicode。但是將cp1251編碼更改為之後utf8

\usepackage[utf8]{inputenc}

編譯停止並顯示錯誤訊息，指示有以下問題\MakeShortVerb{\§}：

! Missing \endcsname inserted.
<to be read again> 
                   \protect 
l.8 \MakeShortVerb{\В§}

? h
The control sequence marked <to be read again> should
not appear between \csname and \endcsname.

Sorry, I already gave what help I could...
Maybe you should try asking a human?
An error might have occurred before I noticed any problems.
``If all else fails, read the instructions.''

! Package inputenc Error: Keyboard character used is undefined
(inputenc)                in inputencoding `utf8'.

See the inputenc package documentation for explanation.
Type  H <return>  for immediate help.

l.8 \MakeShortVerb{\В§}

? r

如何繞過這個問題？沒什麼好說的，我仍然想用作§短逐字文字的分隔符號。shortverb包與utf8編碼相容嗎？

Answer 1

@egreg 又太快了。但我已經準備好午餐了...

\documentclass{article}

\usepackage[T1,T2A]{fontenc}
\usepackage[english,russian]{babel}

\usepackage[utf8]{inputenc}

%\usepackage{shortvrb}

\makeatletter
\DeclareUnicodeCharacter{00A7}{\IgorSVerb}
\def\IgorSVerb{\begingroup\def\IgorSVerb{\verb@egroup\endgroup}\verb^^a7}
\makeatother


\begin{document}
Hello

§\begin{i}$&^\}{"'çÂ\]%§

§\begin{i}$&^\}{"'çÂ\]%§

\selectlanguage{english}

§\begin{i}$&^\}{"'çÂ\]%§

§\begin{i}$&^\}{"'çÂ\]%§<

\end{document} 

Answer 2

問題是，在 UTF-8 中，§是兩個位元組長，但\MakeShortVerb只需要一個。

我能提供的最好的資訊如下：

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[T1,T2A]{fontenc}
\usepackage[english,russian]{babel}

\begingroup\uccode`~="C2 \uppercase{\endgroup
\DeclareUnicodeCharacter{00A7}{\verb~}}
\begingroup\uccode`~="A7 \uppercase{\endgroup\def~}{}

\begin{document}

§\begin{i}§

§{-{\§

\end{document}

限制是 UTF-8 中以 為前綴的字元不能<C2>出現在逐字文字中：禁止字元清單為

¡¢£¤¥¦§¨©ª«¬®¯°±²³´µ¶·¸¹º»¼½¾¿

即 Unicode 範圍00A1– 00BF.
