I don't understand why the following regular expression replacement
gobbles the first two characters.

    \tl_new:N \l_arg_tl
    \regex_const:Nn \c_slash_regex_tl    { / }
    \tl_set:Nn \l_arg_tl {1234/5678/9012}
    \regex_replace_all:NnN \c_slash_regex_tl {\c{textbackslash}} \l_arg_tl
    \regex_use:N \l_arg_tl

It gives me 34\textbackslash5678\textbackslash9012.

Thanks in advance for your help.

Regards,
