These are zone IDs, so I'd rather want to keep them unchanged.
I think there are some applications which store the zone IDs in persistent 
data.  In these applications, any changes in zond IDs will require mapping 
table for backward compatibility support.

Anyway, I'd like to address that these zone IDs are captured in the Common 
Locale Data Repository ( ) and these region 
names are localized (timezones - exemplarCity... of course these localized 
names are represented by Unicode!).  The latest version of CLDR includes 
local names, for example, "Montreal" in French locale is "Montréal".  At 
this moment, the coverage of localization is not great, but it is 
improving in every CLDR releases.

In my opinion, zone IDs should be stable and based on common English 
spelling and supporting native/localized city names via separated bundles 
such as CLDR timezones data.
