I know they are used by some in differential geometry, as I recall it, in order to indicate metric conversions (the coordinate free version of shifting tensors up/down). In some sense the idea is intuitive, even though, at first, it looks out of place. Actually, I think it can be problematic moving out any of the already existing glyphs from the math encodings, before first positively ensuring that they are not used as math symbols. People may have started using them as math symbols, simply because they are accessible, for example. Perhaps such symbols should be classified as "sporadic", with their own math encoding. Hans Aberg
