Thanks Brian - I did wonder if it were I18n related, but  'man bash'   
searched for $" only produced this:

extquote
         If set, $'string' and $"string" quoting is performed within $ 
{parameter}
         expansions  enclosed  in  double  quotes. This option is  
enabled by default.

I hate incomplete man pages.
