well, I'm not sure I parse this line. To me "code" implies more a number 
than something like "other". I'm fine with statements like "character 
category <other>" but less so with "category code <other>"

or is the above to read as

     category code \meta{other} (12)

if you want to go for symbolic then you could have

   \char_show_category:n {x}         -> <letter>

and drop "code" from the cs name
