Does someone have a little ruby script that will read a file in  
UTF-8/UTF-16/UTF-32 (my choice) and search for all the characters  
between  
0x7f-0xffffff and convert them to an ASCII digit string that begins with  
“&#” and ends with “;” and output the whole thing? If not, could someone  
tell me how to write one?

How about a script to do the inverse?

Thanks!

Siegfried,

There is a wrapper library for the standard iconv that takes care of  
this stuff:

[http://www.ruby-doc.org/stdlib/libdoc/iconv/rdoc/index.html](http://www.ruby-doc.org/stdlib/libdoc/iconv/rdoc/index.html)

Take a look at:

Best regards,
