Lightroom: always case sensitive for extended characters: øæå ÆØÅ

I am teaching Lightroom in my local Photoclub, and we discovered something we think is a bug.

Lightroom is case sensitive for a-Z, but in Norway we have 3 more letters. æøå og ÆØÅ. And these letters are treated as special characters.

When I try to search for keyword, I have to search with correct case.

This is very annoying. It will be the same for Danish users.

Best regards,

I would suggest that a lot more than 2 people have problems in the way LR handles letters carrying accents. In French it so happens that capital letters don't usually carry accents and adding an accent to an A, E, I and U isn't particularly easy, so people don't usually bother. However the way that LR handles accents and localisation specificities such as these Norwegian characters indicates that Adobe hasn't put as much thought into this matter as, I think, it should.

I am pretty sure that this bug affects most of non-english speakers who uses own native language for keywording with upper case letter for proper nouns.

As a programmer, I can only guess that there's something wrong with routines that Lightroom uses for comparing words. Obviously only (ancient) 7 bit US-ASCII character set is taken account in incase sensitive comparison and all other characters are treated like a different characters.

I don't know why only few bug reports exists. Perhaps most users doesn't realize what really is wrong and just tries to live with a bug when it troubles.
(for making searches work, one can always add lower case version of keyword to synonyms).
However, this doesn't help with keyword list's filtration.

This bug should be relative easy to fix... For those who uses language that is written in some form of latin alphabets.

"there's something wrong with routines that Lightroom uses for comparing words"

Indeed. The LR plugin SDK's function LrStringUtils.lower() is to supposed to return the lower-case version of a string, but it does so only for ASCII letters. E.g. LrStringUtils.lower ("Б") returns "Б", not "б".

Part of this problem has been fixed.  The Lua function LrStringUtils.lower ("Б") now correctly returns "б".

However, searching still doesn't properly ignore case.  E.g. doing "Any Searchable Field Contains б" doesn't match a photo containing "Б" in its caption field.

Tested in CC 2015.12 / OS X 10.12.6.

So 6 years on we have Lightroom Classic CC and Lightroom CC and we still don't have a fix to this problem ! Admittedly implementing a solution is unlikely to allow Adobe to sell more subscriptions but, at a time when people are asking themselves whether sticking with LR is a good idea, a little bit of "bonne volonté" (goodwill) would not be amiss. Surely there's a trainee somewhere who could prove his worth by implementing the correction.

At this point, I think it's very unlikely Adobe will fix these long-standing bugs and issues in Library.  Victoria Bampton (Lightroom Queen), who is very plugged-in to Adobe, wrote, "Future development of Lightroom Classic is being refocused on improving performance and enhancing the editing tools."  So whatever "focus" there was previously on Library, it is diminished going forward.
