去标记字符串中 _ 下划线后的连字符

Question

语境：在我的文档中，我使用引用机制来引用个人参考资料。我定义了一个\citeref{}宏来处理逗号分隔的参数列表。后者具有以下结构：abc_123。宏的目的\citeref是遍历参数列表，做一些黑魔法（MWE 中未表示），最后在方括号内打印参数列表。因为参考资料中有下划线，所以我\detokenize将它们排版。

问题：-like 引用的连字符abc_123不是最佳的。值得注意的是，下划线后没有启用换行符_。然而，使用该hyphenat包并不有效，因为字符串被去标记化了。

问题：如何在去标记化的字符串中的下划线后启用换行/连字符？

\documentclass[a5paper]{scrartcl}
    \usepackage[T1]{fontenc}

    \usepackage{etoolbox}
    \newcommand{\citeref}[1]{

        \detokenize{#1}%
    }

    \usepackage{hyphenat}
\begin{document}
    Usually, it works fine: either for single \dots\dots\dots\dots\citeref{abcabc_123} or for multiple references \dots\dots\dots\dots\citeref{abc_123, def_456}.

    However, for longer references, a hyphenation would be welcome after the underscore: \citeref{abcdefghijklmnopqrstuvwxyz_12345678910111213}.

使用url包代替\detokenize。

\documentclass[a5paper]{scrartcl}
    \usepackage[T1]{fontenc}
    \usepackage[utf8]{inputenc}

    \usepackage{etoolbox}
    \usepackage{url}
    \DeclareUrlCommand\citerefurl{\urlstyle{same}}
    \newcommand{\citeref}[1]{
        % cf. https://tex.stackexchange.com/a/87423/64454; https://tex.stackexchange.com/q/367418/64454
        [%
            \def\nextitem{\def\nextitem{, }}% Separator
            \forcsvlist\citerefitem{#1}% Process list
        ]%
    }
    \newcommand{\citerefitem}[1]{%
        \nextitem
        \citerefurl{#1}%
    }

    \usepackage{hyphenat}
