Mintty clearly instruct Windows to apply equidistant spacing to achieve fixed-width character cell behaviour. But for certain character ranges, Windows ignores that. Another example for such misbehaviour is the Tibetan block (U+0F00-U+0FFF). Mintty could work around that by rendering characters separately, at a significant penalty for output speed however. Or it could do that only for affected ranges, but criteria to identify them are obscure. Thank you, Thomas. I tried some earlier versions of mintty: * mintty-3.1.0-1 has the same issue * mintty-2.9.6-0 works expectedly in this case.
