For many kinds of data it's more compact, but it can also get longer.

It's slightly more complex than that.

There are encodings that can easily be round-tripped to Unicode and 
back, but for which there are several ways to do so.

For example, there are minor ways in which the mapping from Shift_JIS 
(the traditional Japanese encoding on the PC and the Mac) to Unicode and 
back differ for various systems. See e.g. 
http://icu-project.org/charts/charset/roundtripIndex.html#aix-IBM_932-4.3.6 
(cp932 is the numberical code for Shift_JIS).

This means that you can avoid certain problems by not converting to 
Unicode. You know that one and the same Shift_JIS codepoint will always 
be treated the same. Some programmers and users, especially in Japan, 
care a lot about this. Ruby can deal with this.

On the other hand, there are many cases where you have to work in 
Unicode (in particular Web stuff and everything that potentially mixes 
e.g. Japanese with data from other cultures). Ruby is well prepared for 
this, too.


Regards,   Martin.
