This is correct.

Not at all. They always show the font without any cmap applied,
because there isn't a cmap with the tag you are specifying at the
command line. As soon as you will have implemented a Unicode cmap,
`-e unic' will work also.

Set a break point at `FT_Get_Char_Index' and check the return value.
For example, the function returns 0 if argument `charcode' is zero.
This is wrong, of course, since it should return value 52 (which is
the glyph index of glyph `Γ'). Character code 1 should be mapped to
glyph index 53, code 2 to index 54, etc., etc.
