替换数学字体中的几个字母

Question

我需要用 排版整个文档sourcesanspro，包括公式。我知道有很多人反对这样做，但在这个特定情况下，这样做是有意义的。

我的问题是（就像网络上很多地方经常问到的那样），我没有找到合适的无衬线数学字体。我在网上搜索了几个小时，测试了很多种可能性（arec. cmbright，iwona...），但最终还是使用了sansmath。

据我所知sansmath，它使用默认的无衬线字体系列来排版公式。问题是，它sourcesanspro不包括希腊字母或像黑板字体这样的符号。

是否可以手动用其他字体的希腊字母替换数学字体的几个符号，例如希腊字母？

到目前为止，这是我的 MWE：

\documentclass{scrartcl}

\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{amsmath, amssymb}

\usepackage[default]{sourcesanspro}

\usepackage{sansmath}
\sansmath

\begin{document}


\noindent
ABCDEFGHIJKLMNOPQRSTUVWXYZ \\
abcdefghijklmnopqrstuvwxyz \\
$abcdefghijklmnopqrstuvwxyz$ \\
$ABCDEFGHIJKLMNOPQRSTUVWXYZ$ \\
$\alpha\beta\gamma\delta\epsilon\varepsilon\zeta\eta\theta\vartheta\iota\kappa\varkappa\lambda\mu\nu\xi o\pi\varpi\rho\varrho\sigma\varsigma\tau\upsilon\phi\varphi\chi\psi\omega$ \\
$\Gamma\Delta\Theta\Lambda\Xi\Pi\Sigma\Upsilon\Phi\Psi\Omega$ \\
$\mathbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$
\[
  \frac{1}{2\pi i}\int_\gamma f = \sum_{k=1}^m n(\gamma;a_k) \cdot \text{Res}(f;a_k).
\]

\end{document}

\DeclareSymbolFont这使用 Iwona 表示希腊语，如果您想要不同的字体，请更改字体系列。

\documentclass{scrartcl}

\usepackage[ngerman]{babel}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{amsmath, amssymb}

\usepackage[default]{sourcesanspro}

\usepackage{sansmath}
\sansmath

个人想法无衬线数学只有在演示中才可以对齐。
