XeLaTeX is Unicode aware and can handle Unicode strings. Therefore, I fail to see
why you are doing things this way. The LGR font encoding is an ancient hack that
has no usage anymore.

Of course, in Unicode engines the default captions section
apply, not the captions.licr subsection.

I think that it is absolutely correct that you build in continuing support
for old encodings that may no longer be used with new documents.

The existence of old documents using such encodings certainly
warrants this — especially in the case of archives that process
old (La)TeX sources to create PDFs on the fly.

It is quite possible that in future these will be required to conform
to modern standards, rather than just reproduce exactly what those
sources did in past decades. Then there is the issue of old documents
being aggregated with newer ones, for “Collected Works”-like publications.

It is quite wrong to say that because we now have newer, better methods
that those older methods should be discarded entirely.

I’m facing exactly this problem, adapting  pdfx.sty  to be able to translate
Metadata provided in old encodings: KOI8-R, LGR, OT6 etc.
automatically into UTF-8, because the latter is required by XMP for
requirements to satisfy PDF/A, PDF/X and PDF/E standards.


Keep up the good work.
