Imaginary entity rendering in MathML

Imaginary entity rendering in MathML

[nico]

Hello,

The following MathML test case (rec-arg1) using newmml does not render the  
imaginary entity ⅈ correctly. It is shown as a minus ("-") instead  
of "i". I have this behaviour for any test using this entity.

<math>
       <apply>
         <arg/>
         <apply>
           <plus/>
           <ci> x </ci>
           <apply>
             <times/>
             <cn> &#x02148; </cn>
             <ci> y </ci>
           </apply>
         </apply>
       </apply>
     </math>

Regards,
BG

I guess the problem is that the vector unic-033 (=hex 21) only defines
the arrow part, that starts at 0x2190 ?

Probably.  This vector is far from complete.  I've tried to be as
thorough as  possible, but there simply isn't TeX equivalents for all
symbols in that vector.  At least not ones that I have been able to
find.

but imaginary i cum suis should be possible

They would need \definemathsymbol lines as well then, right?

sure, they can be modeled after the x-newmme.tex entries

If possible, the followings are useful too in math (at least there are  
used in the MathML suite ;-):

&#x0210F; "h" Planck's constant (\hslash in latex)
&#x02146; "d" for use in differentials
&#x02147; "e" exponential base

There are quite a lot more that could be added easily. I'll try ...
