参考书目/apacite 中的冰岛字符有困难

Question

我在编译时无法显示冰岛字符。我使用 texstudio，使用 jabref 作为参考管理器，使用 apacite 作为引用“系统”。一切似乎都很好，只是我的冰岛字符没有显示出来，我尝试做的所有事情都会出错。我试过只使用普通的 bibtex，也试过 biblatex，但错误越来越多……无论如何，这是我的完整代码，不长。

\documentclass[12pt]{article} % Default font size is 12pt, it can be changed here


\usepackage[T1]{fontenc} 
\usepackage[utf8]{inputenc} 
\usepackage[icelandic]{babel}
\usepackage{color}
\usepackage{amsmath} 
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage[left=2.00cm, right=2.00cm, top=2.00cm, bottom=2.00cm]{geometry}
\usepackage{graphicx} % Required for including pictures
\usepackage{apacite}

\geometry{a4paper} % Set the page size to be A4 as opposed to the default US Letter
\usepackage{float} % Allows putting an [H] in \begin{figure} to specify the exact location of the figure
\usepackage{wrapfig} % Allows in-line images such as the example fish picture
\usepackage[shortlabels]{enumitem}
\usepackage{caption}
\usepackage{multicol}
\linespread{1.2} % Line spacing

%\setlength\parindent{0pt} % Uncomment to remove all indentation from paragraphs

\graphicspath{{Pictures/}} % Specifies the directory where pictures are stored
\renewcommand{\topfraction}{.9}
\renewcommand{\bottomfraction}{.9}
\renewcommand{\textfraction}{.1}
\begin{document}


\section{Results} % Sub-section
%------------------------------------------------


\bibliographystyle{apacite}
\bibliography{heimildir2}

\end{multicols}

\end{document}

我遇到的错误如下。

line 21: Package inputenc Error: Unicode char \u8:�s not set up for use with LaTeX stadall, IST EN 12464-1:2011}}}

: No suitable language definition file (icelandic.apc) found.
line 120: Underfull \hbox (badness 10000) in paragraph

有任何想法吗？

更新：以下是 heimildir2.bib 的样子
