Hi,

I'm working on a project to convert several hundred thousand life sciences articles into epub format, and we have run in to a problem with character entities.

Being that these are scientific articles, the characters are from a wide range of Unicode charts, and are essential to transmitting the meaning of the data.

The problem is that in my epub, the character entity inside a table data cell is rendering the @font-face correctly, but inside any other HTML element, the character renders as an empty box on our ipad2s.

So inside div@class="stix", we see boxes, inside td@class="stix", we see the character rendered properly.

      <div class="stix">Let &#x1d542; be a field, which will be either the complex numbers &#x02102; or the finite field &#x1d53d;</div>
      <table id="t31" rules="all">
        <tr>
          <td>&#x1d542;</td>
          <td class="stix">&#x1d542;</td>
          <td>U+1D542 MATHEMATICAL DOUBLE-STRUCK CAPITAL K </td>
        </tr>

My CSS looks like this:

@font-face {
    font-family: 'STIX';
    src: url('STIX-Regular.otf') format('opentype');
    font-weight: normal;
    font-style: normal;
    unicode-range:  U+02B0-02FF, U+07C0-07FF,  U+0900-097F,U+0F00-0FD8, U+1D00-1D7F, U+1D80-1DBF, U+1D400-1D7FF, U+1E00-1EFF, U+1F00-1FFE,U+2000-206F, U+20A0-20B8, U+20D0-20F0, U+2300,23FF, U+25A0-25FF, U+2600-26FF, U+27C0-27EF, U+27F0-27FF, U+2900-297F, U+2A00-2AFF, U+2B00-2B59, U+2C60-2C7F ;
}
@font-face {
    font-family: 'STIX-Math';
    src: url('STIXMath-Regular.otf') format('opentype');
    font-weight: normal;
    font-style: normal;
    unicode-range:  U+02B0-02FF, U+07C0-07FF,  U+0900-097F,U+0F00-0FD8, U+1D00-1D7F, U+1D80-1DBF, U+1D400-1D7FF, U+1E00-1EFF, U+1F00-1FFE,U+2000-206F, U+20A0-20B8, U+20D0-20F0, U+2300,23FF, U+25A0-25FF, U+2600-26FF, U+27C0-27EF, U+27F0-27FF, U+2900-297F, U+2A00-2AFF, U+2B00-2B59, U+2C60-2C7F ;
}
 
 
.stix   {
        font-family: "STIX", "STIX-Math", sans-serif;
}

Is it possible that this is a rendering bug, because the character is rendering in the table cell, but not in other elements?

Have I missed something obvious?

Thanks,
Abe
