HashCat and german (or other exotic) passwords? Help please.

I do not quite understand it.
OK. For German umlauts:

-1 c3
-2 84969c9fa4b6bc.

But. How can I include standard ASCII characters? These have no base HEX code, only actual character HEX code:

For example:

U+0061 a - 61 LATIN SMALL LETTER A
U+0062 b - 62 LATIN SMALL LETTER B
U+0063 c - 63 LATIN SMALL LETTER C
U+0064 d - 64 LATIN SMALL LETTER D
U+0065 e - 65 LATIN SMALL LETTER E
U+0066 f - 66 LATIN SMALL LETTER F
U+0067 g - 67 LATIN SMALL LETTER G

As:
-3 61626364656667 ????

And the the mask: ?1?2?3 He??? I do not understand!
