[Jprogramming] String sort, possible bug

[David Mitchell]

This is documented (see Rank sentence in the doc):

https://code.jsoftware.com/wiki/Vocabulary/slashco#dyadic

The order of priority for ordering-up is:

     Type: numeric or empty, symbol, character (byte or unicode), and boxed, are 
so ordered
     Rank: lower comes before higher
     Values: compared after padding with fills to the same shape
         Symbols are compared based on their symbol index, not the character 
lists they represent.

Cheers,
David
