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. Ticker On Fri, 2021-12-03 at 12:03 +0000, Gerd Petermann wrote:

Hi Ticker,

thanks for the hint. So it's probably better to throw an exception in setStrength()?

Hi Gerd

Beware that the sort with keys (as used in all of Mdr) only sorts to the TERTIARY level, so doing a IDENTICAL scan (either with collator or .equals()) can give strange results as IDENTICAL entries might not be adjacent.

Version mkgmap-r4829 was committed by gerd on Fri, 03 Dec 2021 BRANCH: mdr2 - document that getCollator creates a new instance of SrtCollator - force and document that the SrtCollator constructor sets strength to TERTIARY - if strength is set to IDENTICAL return String.compareTo() instead of 0 when strings are TERTIARY equal (just for experiments)
