消失的字符 Xelatex?

消失的字符 Xelatex?

我注意到,当我编译 .tex 文件 (xelatex -- biber -- xelatex) 时,几个字符 (如 π 和 Λ) 会丢失。以下是我得到的结果:

[1] P. del Amo Sanchez 等人“寻找破坏重子数和轻子数的衰变B0+c −、B−− 和B− ̄−”。见:Phys.Rev. D83(2011 年),第 091101 页。

[2] JP Lees 等人。“使用初态辐射测量反应 e+e−K+K−+−、K+K−00 和 K+K−K+K− 的截面”。在:(2011 年)。* 临时条目 *。

标题应该是这样的:

[1] 寻找重子数和轻子数破坏衰变 B0→Λ+cℓ−、B−→Λℓ− 和 B−→Λˉℓ−。(见http://inspirebeta.net/record/884880

[2] 使用初态辐射测量的反应 e+e−→K+K−π+π−、K+K−π0π0 和 K+K−K+K− 的截面。(见http://inspirebeta.net/record/892684

这是我的 .tex 文件:

您的输入有误:应该是

\setmathfont{Asana Math}

并不是\setsansfont
