鉴于这网站，这个命令\AA就是我要找的。但是它只是生成rA一个圆圈，而不是在 A 的顶部顶点上放置一个圆圈。我该如何解决这个问题？我想在参考书目中正确显示某人的名字。
以下是 MWE：

上面的例子抛出了这些错误：
Use of \@item doesn't match its definition ...itenamefont {\AAo~kerman}}]{Bonetti2009}
Argument of \@rsbox has an extra } ...itenamefont {\AAo~kerman}}]{Bonetti2009}
Paragraph ended before \@rsbox was complete ...itenamefont {\AAo~kerman}}]{Bonetti2009}
Incomplete \iffalse; all text was ignored after line 1076 ...itenamefont {\AAo~kerman}}]{Bonetti2009}
Forbidden control sequence found while scanning text of \write ...itenamefont {\AAo~kerman}}]{Bonetti2009}
参考书目部分是使用 BibTeX 自动生成的。更改\AAo~为{\AAo}可解决问题。但我宁愿让它自动完成。如果能让\AA{}它自己工作就更好了。
答案1
不要重新定义，\r因为这是“å”上使用的“环”。
