带有 \symtt （或 \mathtt）的希腊打字机字符

Question

我想要在数学模式下使用希腊打字机字符unicode-math。

我使用具有希腊字符的字体：

\setmonofont{NewCMMono10}[
    Extension           = .otf,
    UprightFont         = *-Regular,
    ItalicFont          = *-Italic.otf,
    BoldFont            = *-Bold.otf,
    BoldItalicFont      = *-BoldOblique.otf,
    SmallCapsFeatures   = {Numbers=OldStyle}
]

但以下方法均不起作用：\symtt{\Omega}，\symtt{Ω}（这两个方法生成正常的 Omega），\mathtt{\Omega}（这个方法生成一个方框，?好像字符丢失了一样）。

添加这个：

\setmathfont{NewCMMono10-Regular.otf}[
    range               = {tt},
]

没有帮助。

Answer 1

\symtt不幸的是，它仅限于 Unicode 指定的字符集，但您可以将字体声明为数学字母表：

\documentclass{article}

\usepackage{unicode-math}

\setmonofont{NewCMMono10}[
    NFSSFamily=ncmtt,
    Extension           = .otf,
    UprightFont         = *-Regular,
    ItalicFont          = *-Italic.otf,
    BoldFont            = *-Bold.otf,
    BoldItalicFont      = *-BoldOblique.otf,
    SmallCapsFeatures   = {Numbers=OldStyle}
]

\SetMathAlphabet\mathtt{normal}{TU}{ncmtt}{m}{n}
\DeclareMathAlphabet\mathttit{TU}{ncmtt}{m}{it}

\begin{document}
\showoutput

$\mathtt{abc αβγ}$
$\mathttit{abc αβγ}$

\end{document}

Answer 2

您可以定义数学字母表。这里我还介绍了如何在输入中支持标准名称，这样就不必被迫使用希腊字符。

\documentclass{article}
\usepackage{unicode-math}

\setmonofont{NewCMMono10}[
    NFSSFamily          = ncmtt,
    Extension           = .otf,
    UprightFont         = *-Regular,
    ItalicFont          = *-Italic.otf,
    BoldFont            = *-Bold.otf,
    BoldItalicFont      = *-BoldOblique.otf,
    SmallCapsFeatures   = {Numbers=OldStyle}
]

\DeclareMathAlphabet{\mathttinner}{TU}{ncmtt}{m}{n}

\ExplSyntaxOn
\NewDocumentCommand{\xmathtt}{m}
 {
  \mathttinner { \tl_map_function:nN { #1 } \sparusaurata_mathtt:n }
 }

\cs_new_protected:Nn \sparusaurata_mathtt:n
 {
  \str_case:nnF { #1 }
   {
    {\Alpha}{Α}    {\Beta}{Β}   {\Gamma}{Γ}    {\Delta}{Δ}
    {\Epsilon}{Ε}  {\Zeta}{Ζ}   {\Eta}{Η}      {\Theta}{Θ}
    {\Iota}{Ι}     {\Kappa}{Κ}  {\Lambda}{Λ}   {\Mu}{Μ}
    {\Nu}{Ν}       {\Xi}{Ξ}     {\Omicron}{Ο}  {\Pi}{Π}
    {\Rho}{Ρ}      {\Sigma}{Σ}  {\Tau}{Τ}      {\Upsilon}{Υ}
    {\Phi}{Φ}      {\Chi}{Χ}    {\Psi}{Ψ}      {\Omega}{Ω}
    {\alpha}{α}    {\beta}{β}   {\gamma}{γ}    {\delta}{δ}
    {\epsilon}{ε}  {\zeta}{ζ}   {\eta}{η}      {\theta}{θ}
    {\iota}{ι}     {\kappa}{κ}  {\lambda}{λ}   {\mu}{μ}
    {\nu}{ν}       {\xi}{ξ}     {\omicron}{ο}  {\pi}{π}
    {\rho}{ρ}      {\sigma}{σ}  {\tau}{τ}      {\upsilon}{υ}
    {\phi}{φ}      {\chi}{χ}    {\psi}{ψ}      {\omega}{ω}
    {\vartheta}{ϑ}
    {\varsigma}{ς}
    {\varphi}{ϕ}
    {\varpi}{ϖ}
   }
   {#1}
 }

\ExplSyntaxOff

\begin{document}

$\xmathtt{abcαβγφϕΩ\alpha\beta\gamma\phi\varphi\Omega\varsigma}$

\end{document}

根据您的喜好或选择的字体，您可能想要将希腊字符替换为\phi和\varphi。
