[Maxima-discuss] How to set unicode characters for variables

[ehm <eri...@gm...>]

I would like to use the unicode character for hbar, but this happens...

(%i2) M: matrix([a,b],[c,d]);
                                   [ a  b ]
(%o2)                              [      ]
                                   [ c  d ]
(%i3) 1/hbar * M;
                                [  a     b   ]
                                [ ----  ---- ]
                                [ hbar  hbar ]
(%o3)                           [            ]
                                [  c     d   ]
                                [ ----  ---- ]
                                [ hbar  hbar ]

Looks good, this is what I expect. But now...

(%i4) hbar: unicode("latin small letter h with stroke");
(%o4)                                  ħ
(%i5) 1/hbar * M;
                                   [ a  b ]
                                   [      ]
                                   [ c  d ]
(%o5)                              --------
                                      ħ

If I do this without unicode variables it works:

(%i9) hbar: g;
(%o9)                                 g
(%i10) 1/hbar * M;
                                  [ a   b  ]
                                  [ --  -- ]
                                  [ g   g  ]
(%o10)                            [        ]
                                  [ c   d  ]
                                  [ --  -- ]
                                  [ g   g  ]


Why is the unicode character not behaving as a normal symbol?

Thanks,
