I cannot confirm since I get
Assertion failed: (l_fonts[1] != 0), function read_char_packets, file
../../../source/texk/web2c/luatexdir/font/luafont.c, line 881.

Might be related, but solving one won't solve the other one.

If the font comes with some weird encoding, then you also need to
write the whole slot-to-unicode mapping.
See for example:
fonts.enc.math["tex-sy"] = {
[0x0002D] = 0x00, -- -
[0x02212] = 0x00, -- -
-- [0x02201] = 0x00, -- complement
-- [0x02206] = 0x00, -- increment
-- [0x02204] = 0x00, -- not exists
--~ [0x000B7] = 0x01, -- cdot
[0x022C5] = 0x01, -- cdot
[0x000D7] = 0x02, -- times
[0x0002A] = 0x03, -- *
[0x02217] = 0x03, -- *
[0x000F7] = 0x04, -- div
[0x022C4] = 0x05, -- diamond
[0x000B1] = 0x06, -- pm
[0x02213] = 0x07, -- mp
There is
mathematics.make_font ( "charter-math", {
{ name = "file:bchr8a", features = "virtualmath", main = true },
-- { name = "md-chr7m.tfm", vector = "tex-mr" },
{ name = "md-chri7m.tfm", vector = "tex-mi", skewchar=0x7F },
{ name = "md-chri7m.tfm", vector = "tex-it", skewchar=0x7F },
{ name = "md-chr7y.tfm", vector = "tex-sy", skewchar=0x30,
parameters = true },
{ name = "md-chr7v.tfm", vector = "tex-ex", extension = true },
{ name = "msam10.tfm", vector = "tex-ma" },
{ name = "msbm10.tfm", vector = "tex-mb" },
} )
But I'm not sure if all of the fonts are right (I need to figure out
how to compile the example in the first place). A way to check is to
run the following with MKII and compare both for example:
\showfont[md-chr7m.tfm]
\showfont[rm-lmr10]
