I am not happy with the presence of the po_document/pl.iso-8859-2.po file in the Texinfo sources. This was added in commit fe9bd340 (2023-08-06). The reason is that it is unlike all the other translation files in that directory, in that the file has not been provided by translators. It has only been placed in that directory to allow a test to run (t/formats_encodings.t 8bit_document_translations).
This file will not automatically be kept up-to-date with the real Polish translation. In the (unlikely?) event of anybody generating Polish output in the ISO-8859-2 encoding, they may get out-of-date translations, which would not be the fault of the Polish translation team. It's not clear to anybody looking at the contents of po_document where this file comes from and they might assume that they could update the translation files by deleting all *.po files first. I see several possible solutions: * Remove the file and the associated test. That's my favoured option. * Get the test to access the translation file elsewhere, somehow, but do not otherwise use or install this file. (I don't know how this would be done.) * Add Makefile rules to generate the file. The commit message says the file was produced "using iconv and manual edition" so it is not clear if it is easy to generate the file automatically from pl.po. If I do "diff pl.po pl.iso-8859-2.po" then most of the changes are either recoding of translations or updates to the header fields but there are a small number of other changes too. Any comments/preferences?
