<br>
theory.html doesn't appear to address this.<br>
<br>
On 2008-03-18, some name changes were made:<br>
<br>
Calcutta -> Kolkata<br>
Saigon -> Ho_Chi_Minh<br>
<br>
Both reflect changes made well before 2008; for example, the respelling of Kolkata occurred in 2001:<br>

<br>
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.<br>
<br>
> 2) How to handle any alias to the old name(s), when the official Path is to be changed (per #1)?<br>
<br>
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).<br>
<br>
> 3) What historical precedents are there on this matter (I've been trying to look through the change logs), to further validate justification (of #1)?<br>
<br>
Perhaps Calcutta -> Kolkata, although that one may not have been as politically sensitive as this one.</div>
