On the first and last line are shifted because you don’t have protrusion values
for letters
at the begin of the other lines as can be seen in this table (from
font-ext.lua):
vectors['alpha'] = {
[byte("A")] = { .05, .05 },
[byte("F")] = { 0, .05 },
[byte("J")] = { .05, 0 },
[byte("K")] = { 0, .05 },
[byte("L")] = { 0, .05 },
[byte("T")] = { .05, .05 },
[byte("V")] = { .05, .05 },
[byte("W")] = { .05, .05 },
[byte("X")] = { .05, .05 },
[byte("Y")] = { .05, .05 },
[byte("k")] = { 0, .05 },
[byte("r")] = { 0, .05 },
[byte("t")] = { 0, .05 },
[byte("v")] = { .05, .05 },
[byte("w")] = { .05, .05 },
[byte("x")] = { .05, .05 },
[byte("y")] = { .05, .05 },
}
