[mkgmap-dev] [mkgmap-svn] Commit r4829: - document that getCollator creates a new instance of SrtCollator

Fri Dec 3 15:26:08 GMT 2021

Hi Gerd

My view is that should work towards collator.compare everywhere,
initially leaving the strength unchanged or to match usage elsewhere
for similar entities. This might give slightly different results
compared with MapInstall, but the question is "Does it work"?

If it doesn't, maybe the sortkeys will need extending to handle
IDENTICAL.

If it does work, then start fixing the reasons why SECONDARY can't work
without other changes elsewhere.
