Re: UTF to unicode conversion

Fri, 02 Jul 2004 07:07:51 -0700 

Hello,

Mike Ayers has written:
Who said that Unicode is high-tech?
Here is a device to generate UTF-8 that employs traditional tools such as ASCII art, paper, scissors, glue, brain. 

Attached is a similar device for converting Unicode scalar values
to UTF-16 (UTF-16BE, that is, but you could easily add a final step
to compute UTF-16LE, or to add a BOM).

Definitely, the world has longed for this, for years ;-)  Enjoy!

Cheers,
  Otto Stolz
