I think their understanding would be focused on the encoding for their language and a relatively narrow set of problems. I've encountered name issues in CJK countries that keep names in native encoding due to an assumption that full names fit within a couple of characters with no need for any spaces or punctuation. Some systems might be designed to be "accommodating" and take even up to 8 or 10 characters! There was one train system where my name had at least four different iterations through the tickets I collected, with different ordering of first and last names and truncating.
