If you are using a mono-type font, this worked for me:

#local _t1 = text { ttf "fontname.ttf" "A" 1.0, 0 }
#local _t2 = text { ttf "fontname.ttf" "AA" 1.0, 0 }
#local _t1sz = max_extent(_t1) - min_extent(_t1);
#local _t2sz = max_extent(_t2) - min_extent(_t2);
#local _unit_width = (_t2sz - _t1sz).x;

text { ttf "fontname.ttf" "What the heck?" 1.0, -2*unit_width*x }
text { ttf "fontname.ttf" "What the heck?" 1.0, <-unit_width, -1, 0> translate
<0, 14, 0> }
