Dollar character before double quotes in Bash

I recently read some bash code, echo $"asdf", what is $ for?

What is the difference between $"asdf" and just "asdf"?

As documented in the bash manual, it is used for localization:

A double-quoted string preceded by a dollar sign (‘$’) will cause the string to be translated according to the current locale. If the current locale is C or POSIX, the dollar sign is ignored. If the string is translated and replaced, the replacement is double-quoted.
