20 竖直积分号的设置问题

谢谢回答，我的意思是这个oiint要是euler格式下的积分号，基于宏包varint如何设置，或者如何去更改，宏包里面没有给出oiint的设置，不知道是本来就没有，还是忘记设置了。并没有打算去用其他的字体哈.

从这个链接(需要魔法)下载到李清老师的varint.sty宏包，其中选项euler将设置\let\vari@upint@=u \chardef\vari@upint=1:

其对应的数学字体配置为:

    \PackageInfo{varint}{Using euler-int style}
    \DeclareFontFamily{OMX}{eu@int}{}
    \DeclareFontShape{OMX}{eu@int}{m}{n}{
      <-7.5> euex7  <7.5-8.5> euex8  <8.5-9.5> euex9  <9.5-> euex10 }{}
    \DeclareSymbolFont{eu@int}{OMX}{eu@int}{m}{n}
    \DeclareFontSubstitution{OMX}{eu@int}{m}{n}
    \DeclareMathSymbol{\vari@intop}     {\mathop}{eu@int}{82}
    \DeclareMathSymbol{\vari@ointop}    {\mathop}{eu@int}{72}
    \def\intkern@{\mkern-7mu}
    \def\intdots@{\mathchoice
        {\mkern-6mu\vari@intdots{.25}\mkern-7mu}
        {\mkern-5mu\vari@intdots{.25}\mkern-5mu}
        {\mkern-5mu\vari@intdots{.25}\mkern-5mu}
        {\mkern-5mu\vari@intdots{.25}\mkern-5mu}}
    \def\ints@b{\mathop\bgroup\let\ilimits@\egroup}
    \newrobustcmd*\upint{\mathchoice
        {\mkern7mu\overline{\vphantom{\vari@intop}\mkern6mu}\mkern-13mu}
        {\mkern3mu\overline{\vphantom{\vari@intop}\mkern6mu}\mkern-13mu}
        {\mkern3mu\overline{\vphantom{\vari@intop}\mkern6mu}\mkern-13mu}
        {\mkern3mu\overline{\vphantom{\vari@intop}\mkern6mu}\mkern-13mu}%
      \int}
    \newrobustcmd*\lowint{\mkern3mu\underline{\vphantom{\vari@intop}\mkern7mu}\mkern-10mu\int}
