This is all true, but it is worth pointing out that ICU includes a
data file that contains (amongst other things) time zone data, Unicode
data, localisation information and other stuff.
The issue there is that *occasionally* the data file needs updating.
For instance when some politician decides that now would be a good
time to change the time zone rules for the United States (as happened
recently). Or when the Unicode specification is revised or bugs are
found in the CLDR data. If you have multiple copies of ICU, each one
will need updating separately... and because the ICU data file is
version specific to some extent, you can't necessarily share the data.
You can avoid this, for the most part, by using Core Foundation or
Cocoa where possible, since that will use the system's copy of the
data which will at least result in consistent behaviour. But if you
use ICU directly, or rely on something that does, and you choose to
bundle ICU with your application, you should be aware of this issue.
Kind regards,
Alastair.
