Transparent and translucent are synonyms. The only way to avoid using an
alpha channel (that I know of) is to make with that low level code and
draw say, only every second pixel of the relevant object. Blending is
not available at all to individual members of the ASCII character set.
(Read the standard.) Some implementation may add effects to text, but
that is not specified by the ASCII character set itself.

Your drawing does indeed lend the illusion of transparency, but note
that the OP wanted transparency on a per-character basis, not on any
larger scale.
