I try to convert xhtml document with mathml formulae with this command:
umcl_cli convert -o out.xhtml -x mathml cmathml test.xhtml
and i have some problems because it was unsuccesfull.

Here is log:

separators :
mi pour y

Problem is with this formulae: <math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mo>±</mo><annotation-xml encoding="MathML-Content"><ci>±</ci></annotation-xml></semantics></math>
because mathematical sign "±" is in <mo> tag. I try replce it with some Strings and if there is mathematical sign transformation is unsuccesfull, but if there is any other string then it is succesfull.

I send you my test file in attachment.

    The '<mo>±</mo>' or '<mo>&#177;</mo>' mathml patern crash umcl and for instance we can just get around the problem replacing the 'mo' tag by a 'mi' or a 'mtext' one in the patern.

    Actually it looks it's only woith the French Braille. We are progressing...
    the problem does not happen when transcribing into Marburg or Nemeth
