As I recall pseudoloc is just randomly picking individual characters to substitute that look like the Latin letters to keep it readable for testing, so it would be something like рг (Cyrillic) ο (Greek)... etc, and can change from run to run. It would also artificially pad or shorten terms to catch cases where the (usually German) term would be much longer or a (usually CJK) term would be much shorter and screw up alignment or breaks.

I seem to remember that it was mostly adding various accent marks / umlauts / etc. to English words so things were indeed readable but I'm not going to bet any money on that as I didn't have to actually log in onto those machines super frequently.

Yeah, there were definitely ö and û and © and stuff too, just anything outside the normal 0x20-0x7E.
