The characters are squeezed together because the font has wrong metrics.

When you use a Type 1 math font with ConTeXt MkIV all characters in the different
files are mapped to the corresponding unicode points but these mappings aren’t
complete (e.g. bold uppercase greek letters aren’t mapped).

For some fonts you would also need a custom mapping because not all fonts
put the symbols in the same position.
