Using a collating sequence specified in an LDML file for doing a line sort

Question

I have an LDML file that specifies a collating sequence for a language not listed in /usr/share/locale.

I want to use the collating sequence from the LDML file to do a line sort in Linux.

My preferred tool is the bash sort command

I could also use the Perl Unicode::ICU::Collator if I understood how to set it up with information from the LDML file.

Answer 1

A python (rather than perl) solution is available using the icu library documented at:

and
