Dear JavaScripters:

     There are a number of functions for escaping various characters
and de-escaping them:
          Escape Function          Unescape Function
          ---------------          -----------------
          escape()                 unescape()
          encodeURI()              decodeURI()
          encodeURIComponent()     decodeURIComponent()
There may be others that I am unaware of.

     What I am definitely unaware of is when to use them.  I have not
seen any material on that other than vague (to me) sentences.  They
seem to assume that people already know what they are doing with them.

     Between them and HTML's "&something;", I really could use a good
grounding in the area.

     Pointers please?

Sincerely,

Gene Wirchenko
