我无法显示正确的参考列表 - 一个字母就是不显示。我在 Google 上搜索了可能的解决方案，并更新了字体和软件包，但仍然无法解决这个问题。
以下是 MWE 的内容：
\documentclass[12pt,a4paper,oneside]{article}
\usepackage[T1]{fontenc} % Unicode in references
\usepackage[utf8]{inputenc} % Unicode in references
\usepackage[backend=biber, style=chicago-authordate, autocite=inline,bibencoding=utf8, sorting=nyt, language=false, doi=false, url=false, isbn=false, hyperref=true, maxcitenames=2, maxbibnames=100, dashed=false, uniquelist=false, refsegment=chapter, defernumbers=true]{biblatex}
\bibliography{mylibrary}
\begin{document}
The problem letter \u{g}.
\textcite{javorcik2011migrant}
\printbibliography
\end{document}
mylibrary 文件包含以下内容（该文件保存为 utf-8 编码文件）：

我可以看到许多 Unicode 字符，但就是看不到 ğ。为什么？
我在 OSX El Capitan 上。所有与 TeX 相关的内容都通过 TeXLive 更新。
答案1
与 XeLaTeX 一起使用fontenc是错误的，因为引擎使用基于 Latin-1 的 Unicode 作为最低块，而 T1 与 Latin-1 不一致。
该字形ğ被 T1 覆盖，但它所处的位置无法与 XeTeX 所看到的字形相对应，因为它不在 Latin-1 中。其他字形也有同样的问题；其他在 Latin-1 中的字形在 T1 中的位置不同。
可以使用pdflatex或 loadfontspec代替fontenc。请注意inputenc不会执行任何操作，但最好也将其删除。
\documentclass{article}
\usepackage{fontspec}
\usepackage[<options>]{biblatex}
\addbibresource{mylibrary.bib}
是正确的前导码（添加其余部分）。请注意，\addbibresource建议超过\bibliography（.bib扩展需要使用推荐命令）。
答案2
不要将 fontenc 与 xetex 一起使用，你指定的是 T1 编码字体，这是一种非 unicode 编码，只有 256 个字符，而 biber 和 xetex 需要 unicode，因此你会在日志中看到
Missing character: There is no ğ in font ecrm1200!
ğ 为 U+011f，因此不能出现在仅具有最多 FF 插槽的 T1 编码字体中
相反使用
\usepackage{fontspec}
并删除
\usepackage[T1]{fontenc} % Unicode in references
\usepackage[utf8]{inputenc} % Unicode in references
