I've been trying to figure out different approaches to constructing circles with text inside of them in SLD/GeoServer. Single character font-based "external" symbols work fine, with the "text" part being e.g.:
<PointSymbolizer> <Graphic> <Mark> <WellKnownName>ttf://Arial#0x70</WellKnownName> <Fill> <CssParameter name="fill">#000000</CssParameter> </Fill> </Mark> <Size>7</Size> </Graphic> </PointSymbolizer>
My question is, is it possible to combine several characters into one WellKnownName tag in the hex format? Haven't found anything at least in the SLD documentations / references. Or does one always have to generate several PointSymbolizer entities with single characters accompanied by some offset technique to generate multi-character text symbols? Looking for the cleanest, least-markup approach here.
For instance if I'd want a text "AA" inside a circle, the HEX code would be 4141, but so far it seems one can only single letters, e.g. ttf://Arial#0x41. At least ttf://Arial#0x4141 doesn't seem to work.
Of course one can create texts inside circles with TextSymbolizer but that runs into all kinds of label removal/placement issues.
