biblatex-dw 中上标正面、反面和句号/逗号的字距调整

Question

我创建了三个用于biblatex-dw排版\recto \verso和\rectoverso引用的命令。

如果其中一个命令后面跟着句号或逗号，那么我认为上标和句号/逗号之间的水平间距太宽。

为了弥补这一点，我尝试使用作为独立命令工作的@ifnextchar命令\recto，但不在不同 cite 命令的 postnote 参数内工作biblatex。

我认为这个方法@ifnextchar不起作用，因为biblatex-dw它对后记本身进行了大量重新排列，并在脚注中插入了最后的句号。有什么想法可以达到预期的效果吗？

Test 50\recto. <-- This works

Test 50\recto, <-- To see the effect between the full stop kerning and the not affected comma

Test \fullcite[][50\recto]{Test}. <-- This leads to 5 errors. The final full stop in the footnote should be moved nearer to the superscripted r

Test\footnote{Some remarks. \fullcite[][50\recto]{Test}.} <-- This leads to 5 errors. The final full stop in the footnote should be moved nearer to the superscripted r

Test\footnote{Some remarks. \fullcite[][50\recto]{Test} and \fullcite[][55\recto]{Test}.} <-- This leads to 10 errors. The final full stop in the footnote should be moved nearer to the superscripted r, but the word 'and' shouldn't be affected
