Hello everybody.
Following an advice of @TomP I would like to dedicate some resources in "building a localizing dictionary of Rust error message templates together with their translations. And as a next phase from that maybe create a postprocessor for piped Rust compiler output, which could provide a localized translation of those error messages whose templates were in the dictionary (with any other error messages left untranslated)".
Also I would be more than happy to help translate official documentation and website, but looking at the page contribute translations, there is not much guidance.
On a side note, I would recommend to change "Rust is universal" to something more engaging like "Rust strive to embrace cultural diversity, help us to foster it universally".
Kind regards
