我正在用英语写一篇文章，但我想在参考书目中使用俄语引用一些内容。目前我只需要在文件中使用俄语.bib。我安装了该babel软件包，但如果我尝试编译，文件中的每个西里尔字符都会出现错误.bib，例如：
! LaTeX Error: Command \CYRB unavailable in encoding T1!
和
LaTeX Error: Command \CYRE unavailable in encoding T1
等等。
这是我的文档的开头：
\documentclass[a4paper, 11pt, headings = small]{scrreprt}
\usepackage[T2A,T1]{fontenc} \usepackage[utf8]{inputenc}
\usepackage{natbib} \usepackage{setspace}
\usepackage{lmodern} \usepackage[russian,UKenglish]{babel}
\usepackage{amsfonts} \usepackage{amsmath}
\usepackage{amsthm} \usepackage{rotating}
\usepackage{amssymb} \usepackage{thmtools}
如果我更改字体顺序并在 T1 之后设置 T2A，则一切都可以正常编译，因为西里尔字母可以被识别，但效果不佳，因为使用此字体，一切都不同，定理和类似内容与普通文本没有区别。我如何使用 T1 字体编码，但编译.bib包含俄文字符的文件，如果可能的话仍然使用natbib？这是我的 Bib 文件，俄语文章目前没有评论：

您必须标记条目：
\RequirePackage{filecontents}
\begin{filecontents*}{\jobname.bib}

像往常一样，filecontents环境只是为了使示例自成一体。
