This from the "THE OLDSCHOOL PC FONT RESOURCE", https://int10h.org/oldschool-pc-fonts/readme/#cp437_text, may give a clue as to the difficulty you're having:
"CP437 can't really be mapped to Unicode in a simple 1:1 manner. The culprits are characters 00h-1Fh and 7Fh, which can be interpreted either as control codes or as graphical symbols. Thus there are two widely used mappings: the standard IBM/MS map (which does the former), and Unicode's "IBMGRAPH" map (which does the latter). Trouble is, software that expects one of them may not always play nice with the other one."
