Interesting! the 23-037E3 font (assuming that's what 'chargen.bin' is), if you discount the 6 unused rows of pixels, the first half matches the 23-018E2 vt100 font. Whats more interesting is the second half, which may very well match the missing, undumped 23-094e2 'alternate character generator' rom from the vt100!
It has the section, paragraph, and foreign language characters I'd expect from the VT100-WK 'word processing' version.
