I did some more testing and the result is, that the new FOP 0.95 always has
the same result:
<fo:block text-align="start" font-family="{$Font}"
font-size="20pt" color="{$TitleFontColor}">
<xsl:text>geeeeeeeeeeeeeeeeee</xsl:text>
</fo:block>
No matter if I only set capital letters or only small caps, only "gjy" or
with/without paranthesis, all examples have the same result, i.e. a letter
is always placed at the same horizontal position - no matter if/what other
letters are in the same line/block. In my example font, the text is always
displayed that an "e" is exactly horizontal centered.
As you might argue, that it's more "correct" to center the small letters
like "e", it looks really awkward if a line/block only has a number, because
the digits are also "shifted upwards".
In addition, with the fo:inline "workaround", the whole line/block gets a
bigger height. :-(
