[tz] WSJ follows AP to Kyiv

I'd like to add two data points to the discussion:

1) CLDR 35 added Kyiv as a formal alternative name.  This is the first time that has been done in CLDR.  The English (en.xml) file now has the following:

<zone type="Europe/Kiev">
  <exemplarCity alt="formal">Kyiv</exemplarCity>


2) The English display name given by Windows for this zone is: "(UTC+02:00) Helsinki, Kyiv, Riga, Sofia, Tallinn, Vilnius".  It's a different data set, and is influenced by Microsoft's decision-makers, but is indeed a label that has been applied to a time zone with the Kyiv spelling.

Given these as precedent, I would not be in favor of renaming the Zone but I would be in favor of a Link entry added for Europe/Kyiv (with Europe/Kiev remaining the Zone entry for now).  I get this is backwards from the usual approach, but seems to be a reasonable compromise.

Also, I notice that theory.html doesn't discuss Link entries at all.  Perhaps that should be rectified?

theory.html doesn't appear to address this.

On 2008-03-18, some name changes were made:

        Calcutta -> Kolkata
        Saigon -> Ho_Chi_Minh

Both reflect changes made well before 2008; for example, the respelling of Kolkata occurred in 2001:


The first of those changes is the one closest to Kiev vs. Kyiv - the latter isn't just a respelling, it's a renaming, and apparently also corresponded to the incorporation of some other districts outside what was Saigon into the city.

Presumably, the same way that those other changes were made; a Link line is added to the "backward" file, so the old name remains for backwards compatibility, as a link to the new name (at least if you're using a file system that supports links).

Perhaps Calcutta -> Kolkata, although that one may not have been as politically sensitive as this one.
