Woops! sorry. I did not read everything. I don't understand this 
alignment-baseline. At 
http://www.w3.org/TR/SVG/text.html#AlignmentBaselineProperty I read that it 
does not appy <text but only <tspan. That does not seem logical.

So I have a rectangle whose upper right corner is at 0,0 and width=12.5 and 
height=12.5. The following code does not center it horizontally or 
vertically:

<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="middle" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="central" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="before-edge" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="text-before-edge" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="after-edge" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="text-after-edge" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="ideographic" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="alphabetic" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="hanging" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="central" >&#57350;</tspan></text>
<text x="6.25" y="6.25" text-anchor="middle" class="common-segoe"><tspan 
alignment-baseline="mathematical" >&#57350;</tspan></text>

Could it be a problem with custom font I'm using? OK, I tried the default 
font and removed the class="common-segoe" and that did not help with the 
vertical centering. It looks like the alignment-baseline has no affect! Is 
this a bug? But the horizontal alignment looks good. So maybe there is a 
problem with the custom font I am using? Uggghh... I'm not sure how to fix 
that.
Thanks!
