[xep-support] Incorrect kerning of high quality OpenType fonts

[Jan Tošovský]

Hello Everyone,

I've encountered missing kerning in this example:

<?xml version="1.0" encoding="utf-8"?>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
  <fo:layout-master-set>
    <fo:simple-page-master master-name="simple" page-height="297mm" page-width="210mm">
      <fo:region-body margin="10mm"/>
    </fo:simple-page-master>
  </fo:layout-master-set>
  <fo:page-sequence master-reference="simple">
    <fo:flow flow-name="xsl-region-body">
      <fo:block font-family="Minion Pro">VLTAVA</fo:block>
    </fo:flow>
  </fo:page-sequence>
</fo:root>

Here is the corresponding entry in the xep.xml:

    <font-group xml:base="file:/C:/Program Files (x86)/Adobe/Reader 11.0/Resource/Font/" label="Adobe Fonts" embed="true" subset="true">
      <font-family name="Minion Pro" ligatures="&#xFB00; &#xFB01; &#xFB02; &#xFB03; &#xFB04;">
        <font><font-data otf="MinionPro-Regular.otf"/></font>
        <font variant="small-caps"><font-data otf="MinionPro-Regular.otf"/></font>
        <font style="oblique"><font-data otf="MinionPro-It.otf"/></font>
        <font weight="bold"><font-data otf="MinionPro-Bold.otf"/></font>
        <font weight="bold" style="oblique"><font-data otf="MinionPro-BoldIt.otf"/></font>
      </font-family>
    </font-group>

Btw, that Reader XI's path is used just for demonstration purposes as it can be tested by everyone. License doesn't permit this font for production.

I've found the following old thread (2004) mentioning missing kerning support for OpenType/CFF fonts
http://services.renderx.com/lists/xep-support/2917.html

Am I facing this issue or there is some mistake in my settings?

Thanks, Jan
