一个用来显示字库里所有汉字的TeX文件

用 TeX 处理这个文件之后你就能看到所有宋体汉字。
假设你的宋体叫做 gbksong, 如果不是请改动第一行。

    /def/ff{gbksong}
    /def/showchar{{/count0=0 /par
    /loop /char/count0{/tenrm/number/count0}
    /advance/count0 by 1 /ifnum/count0<256 /repeat/par}}
    /def/showchinesefont{
    {/count1=1 /loop /bigskip/noindent/tenrm0/number/count1:
    /font/c=/ff0/number/count1 /c /showchar
    /advance/count1 by 1 /ifnum/count1<10 /repeat }
    {/count1=10 /loop /tenrm/number/count1: /font/c=/ff/number/count1 /c /showchar
    /advance/count1 by 1 /ifnum/count1<95 /repeat }
    }
    /showchinesefont
