更新，很晚了
不要这样做。请改用字体。这只会在意想不到且难以调试的地方造成很多麻烦。请参阅另一个答案针对同一问题了解详情。
改变数字零的斜线方向
在这个答案0我学会了如何更改块内数字中斜线的方向texttt。这种方法很好用，但在票务环境中却不行。
注意我们使用 pdflatex（运行两次）。

如您所见，斜线穿过 ，0从左下角到右上角，但我似乎无法让它在名片内部工作。我起初以为这是因为，但将或 的\put文本“原始”地放在 中，即不在 内，也不能解决这个问题：\ticketdefault\ticket\put
\newcommand{\vcard}[1]{\ticket{
Outside \texttt{m0n} with texttt.
\put(30,38){\texttt{#1}}
\put(30,32){\ttfamily #1}
\put(30,26){\ttfamily\catcode`0=\active #1}
}}

您必须0在吸收论点之前激活；我还提出了反向斜线零宏的固定版本。

一种不同的实现方式expl3，不需要辅助命令\vcard，可以避免分组。
