I'm facing a specific sort problem.
There are several thousands of articles sold all over.
Users expect to get a description in local language sorted by their specific collation.
I have simplified the original class to the core fields for this case.
The whole construct serves as multi language lookup table.
It works based on the defined Indices [here only 3 for this example]
The problem to be solved is to have the correct language-specific collation
Some languages overlap nicely (eg. EN + DE) but others (esp. HU) don't match
or are totally separated (e.g. BG in Cyrillic notation)
just see example: https://en.wikipedia.org/wiki/Hungarian_alphabet
There is actually some hand-coded workaround in place to enforce collation but performance is not thrilling.
I hope you have some brilliant suggestions to get better solutions.
