Apologies. I forgot to mention that I was worrying about using the
ICU for the time zone database rather than character sets.
Why does that worry you?

Because my understanding is that the ICU is the source of the time zone
database and will have to be updated every time a time zone changes or
there are changes to the dates for daylight savings time coming into
effect. Here's one of many examples:

I was worrying about recommending a strategy for updating the ICU files
under Windows.
So far I also seem to have learnt:
1. There is no intent to use the Windows 10 ICU library in Firebird.
2. There is a risk of a stealth (ICU) upgrade under Linux if the upgrade
affects indexes that depend upon character set collation sequences.
Neither of which I expected. For Windows, there may need to Firebird
incremental updates to catch up with time zone changes. For Linux, this
is automatic - but beware of index problems...
