如何在 .bib 输出中禁用 \textgreek 的斜体

Question

我想禁用 .bib 文件中希腊文标题的斜体，但不禁用整个文档的斜体。我应该怎么做？

我认为最好的方法是\emph{}在需要时使用希腊字符而不使用\textgreek{}[我只需要几次希腊语斜体]，并禁用斜体选项\textgreek{}，但我不知道如何在主文档的序言中执行最后一个操作。

% !TeX encoding = UTF-8
% !TeX TS-program = xelatex
% !TeX spellcheck = it_IT
% !TeX root = Italics.tex
% !BIB TS-program = biber

@book{Sathas.1872,

 year = {1872-1894},
 title = {\textgreek{Μεσαιωνικὴ Βιβλιοθήκη. Συλλογὴ ἀνεκδότων μνημείων τῆς Ἑλλενικῆς ἱστορίας}},
 volumes = {I-VII},
 address = {\textgreek{Παρίσι}},
 publisher = {\textgreek{Ἑταιρεία Μακεδονικῶν Σπουδῶν}}
}

如果您只想更改某种语言的标题格式，则需要languageid在条目中设置，并在格式化命令中使用来检查\iffieldequalstr。

在SathasA字段中languageid设置为greek，而在SathasB字段中则完全省略：

\documentclass[a4paper,12pt]{article}

\begin{filecontents*}{\jobname.bib}
  @book{SathasA,
    editor = {Sathas, Konstantinos N.},
    date = {1872},
    title = {Μεσαιωνικὴ Βιβλιοθήκη. Συλλογὴ ἀνεκδότων μνημείων τῆς Ἑλλενικῆς ἱστορίας},
    volumes = {I-VII},
    address = {Παρίσι},
    publisher = {Ἑταιρεία Μακεδονικῶν Σπουδῶν},
    langid = {greek}
  }
  @book{SathasB,
    editor = {Sathas, Konstantinos N.},
    date = {1872},
    title = {Μεσαιωνικὴ Βιβλιοθήκη. Συλλογὴ ἀνεκδότων μνημείων τῆς Ἑλλενικῆς ἱστορίας},
    volumes = {I-VII},
    address = {Παρίσι},
    publisher = {Ἑταιρεία Μακεδονικῶν Σπουδῶν},
  }
\end{filecontents*}

\usepackage{fontspec} 
  \setmainfont[Ligatures=TeX,Numbers=OldStyle]{Linux Libertine O}

\usepackage{csquotes}

\usepackage{polyglossia} 
  \setmainlanguage{italian}
    \setotherlanguages{greek,english}
      \setkeys{greek}{variant=polytonic}

\usepackage[style=phys, sorting=none]{biblatex}
  \addbibresource{\jobname.bib}
  \DeclareFieldFormat{title}{% <-- change the format of the title field
    \iffieldequalstr{langid}{greek}{\normalfont{#1}}{\mkbibitalic{#1}}}
    % if langid = greek, then use \normalfont else use \mkbibitalic
  
\begin{document}

\emph{ἄνθρωπος} \autocite{SathasA}
\emph{ἄνθρωπος} \autocite{SathasB}
\printbibliography[title={Bibliography}]
\end{document}

如果您想要希腊语的完整引文（翻译的字符串等），那么请添加 biblatex 选项autolang=other：
