In letters written in the early 20th century, for the German word “bei”, the author commonly uses the abbreviation “ᵇ/”. Currently I typeset as follows:
26.4.17 \textsuperscript{b}/La Selve
The result, however, is an unpleasant space between the superscript “b” and the slash. Of course I could manually adjust space, but I wonder:
Is there a recommended way of typesetting abbreviations like that? Any dedicated package?
