2016 HG: HELP: The sneaky glitch of unicode and the mystery of the right HG address that fails

The sneaky glitch of unicode and 
the mystery of the right HG address that fails
You copy-paste a hypergrid address into the world map.   The map says the place does not exist.  The grid operator (in Europe) says the grid is running and tests the HG address, verifying that it works.  But your copy still does not work.  You can see that you have the right grid address but it does not work for you. Don't blame the Hypergrid.

The scenario where I found it

  • Somebody in Europe posts a hypergrid address in a Google+ community, inviting a visit.
  • I copy-paste that 
  • My world map (in Firestorm) reports that it can't find the place.
  • The grid operator says the grid is running.  
  • This is not a fault of Hypergrid.  What is happening?

Answer

The address is given in Unicode and the World Map in Firestorm expects ASCII.  Although most English text looks the same in either coding scheme, the representations in binary are not all the same.   The firestorm code handling the input address to the world map is not able to read this unicode.  

Workaround 

  • Users:  If a hypergrid address does not work with copy-paste, try typing it in.  
  • Inviters:  Spread the word given above when you post invitations.

Solutions

  • This may be a Firestorm left-over from SL, where HG addresses are not a problem
  • The Firestorm people can easily fix it if they notice it.  
  • Other viewer developers may want to see if they have the same code.   
****************************
Unicode is a computing industry standard for the consistent encoding, representation, and handling of text expressed in most of the world's writing systems. 
-
ASCII abbreviated from American Standard Code for Information Interchange, is a character encoding standard (the Internet Assigned Numbers Authority (IANA) prefers the name US-ASCII[2]). ASCII codes represent text in computers, telecommunications equipment, and other devices. Most modern character-encoding schemes are based on ASCII, although they support many additional characters.
