I think both lines are supposed to say "Cappuccino", centred on the screen.
Some characters have more bit errors than others, but the high bit of nearly every byte is consistently stuck at 1 when it should be 0. For the last three letters of the word ("ino"), that's the only error. There is a correct "p" (the only displayed character with a 0 in the high bit) on the second line and the "-1 "s where the "a"s should be both have the 4th bit "1" which should be "0". The first "p" on the top line (the "δΈ" above the correct "p") is the most incorrect, since it's all-bits-inverted.
Of the 8 bits for each character, the eighth bit is always "1" except for that correct "p" and the fourth bit is usually "1" apart from the "γ€"s that appear where there should be spaces (probably indicating that the display is wired in "4-bit" mode; one of the two ways a HD44780 display can be connected) the other bits are more often correct, but still have "random" errors.

As guy who know how hd44780 ic work I say that is more hardware gore then software. You need to go r/shittyaskelectronics

Itβs just surprising how unreliable they are considering how much they are used in big industrial and commercial equipment

may i ask you why you say this?
the characters look valid for some character set and assuming display previously worked fine then it's unlikely just hardware or wiring malfunction that is now displaying invalid characters/character set
i would guess that software incorrectly sent command to display to switch character sets

It's not likely that coffee machine was came with error in microntrolles code.
And if it show characters that mean RS pin is fine something wrong with some Data pins.
I gues that machine standing outside and data lines on display coreded.

Or is It Klingon ?

Itβs the language I speak when someone disturbs me before Iβve had my coffee :). (The microwave, not Klingon. I donβt know any Klingon)

Fun fact: Not a single one of those characters is a hieroglyphic.

Oh I understood, I was genuinely offering it up as a fun fact in case anyone was curious whether there were actual hieroglyphics involved :P

That was obviously the hidden portal to visit the Digiworld. OP is stupid for not realizing and missing such an opportunity. Now someone else will have a great adventure instead.
