Texto grego referências em inglês

Question

Estou tentando descobrir como poderia funcionar escrever em texto grego e ter referências em inglês. Tentei muito do que encontrei em minha pesquisa, mas nada está funcionando corretamente para mim, pelo menos.

O que eu tenho está abaixo

\documentclass[11pt,a4paper,english,greek,twoside]{hua}
\usepackage{graphicx}
\usepackage{epstopdf}
\usepackage{indentfirst}
\usepackage{verbatim}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amssymb}
\usepackage{latexsym}
\bibliographystyle{ieeetr}
\usepackage{hyphenat}
\usepackage{makeidx}
%\usepackage[iso-8859-7]{inputenc}
%\usepackage[greek]{babel}
%\usepackage[T1, T2A]{fontenc}
%\usepackage[utf8x]{inputenc}
\addto\captionsgreek{%
  \renewcommand{\indexname}{Ευρετήριο όρων}%
}
\makeindex

% 1.5 spacing
\renewcommand{\baselinestretch}{1.2}

% latin text (and greek text)
\newcommand{\tl}[1]{\textlatin{#1}}
\newcommand{\tg}[1]{\textgreek{#1}}
\newcommand{\lat} {\latintext} 
\newcommand{\gre}{\greektext}

\begin{document}
\lat{\bibliography{references}}
\end{document}

Tudo o que você vê comentado no usepackage foram minhas tentativas de forma independente ou combinada. Por favor, se você tiver alguma ideia, me ajude.

Answer 1

Talvez isso funcione para você:

\usepackage{etoolbox}
\AtBeginEnvironment{thebibliography}{\selectlanguage{british}}

Eu não tenho hua.cls, ao que parece. Mas, por exemplo:

\RequirePackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{aa,
  author =     {Me and Myself and I},
  title =      {My Article},
  journal =    {My Journal},
  year =       {2016},
  number =     1,
  volume =     1,
  pages =      {1-20},
}

@article{bb,
  author =     {Us and Them},
  title =      {Our Article},
  journal =    {Our Journal},
  year =       {1996},
  number =     2,
  volume =     2,
  pages =      {1-20},
}
\end{filecontents}
%\documentclass[11pt,a4paper,english,greek,twoside]{hua}
\documentclass[11pt,a4paper,twoside]{article}
\usepackage{graphicx}
\usepackage{epstopdf}
\usepackage{indentfirst}
\usepackage{verbatim}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amssymb}
\usepackage{latexsym}
\bibliographystyle{ieeetr}
\usepackage{hyphenat}
\usepackage{makeidx}
%\usepackage[iso-8859-7]{inputenc}
\usepackage[T1, T2A]{fontenc}
\usepackage[utf8x]{inputenc}
\usepackage[british,greek]{babel}
\usepackage{etoolbox}% <-- normally, I'd load this earlier, but it defines \AtBeginEnvironment...
\AtBeginEnvironment{thebibliography}{\selectlanguage{british}}
\addto\captionsgreek{%
  \renewcommand{\indexname}{Ευρετήριο όρων}%
}
\makeindex

% 1.5 spacing
\renewcommand{\baselinestretch}{1.2}

% latin text (and greek text)
\newcommand{\tl}[1]{\textlatin{#1}}
\newcommand{\tg}[1]{\textgreek{#1}}
\newcommand{\lat} {\latintext}
\newcommand{\gre}{\greektext}

\begin{document}

\tg{Ευρετήριο όρων}
\gre Ευρετήριο όρων

\cite{aa,bb}

\bibliography{\jobname}
\end{document}

Answer 2

Adicione suporte para inglês:

\begin{filecontents*}{\jobname.bib}
@article{uthor2025,
  author={A. Uthor},
  title={Title},
  journal={Journal},
  year=2025,
}
\end{filecontents*}

\addto\captionsgreek{%

Algumas notas.

• Evite a utf8xopção
• T2A é a codificação para cirílico
• epstopdfé carregado automaticamente
• latexsymestá obsoleto

Usei a bookclasse, sem saber hua.

Se você quiser que o título do capítulo da bibliografia esteja em inglês, use

\begin{otherlanguage}{english}
\bibliography{\jobname}
\end{otherlanguage}

Usei \jobnamejunto com filecontents*apenas para tornar o exemplo independente. Você usará seu .bibarquivo.
