To get the equivalent number of underscores you could use the strReplace
function. It's misdocumented in the page Andrea linked to, it actually
takes 4 arguments and not just 2.
css:
> * {
> label: [PROP], [strReplace(PROP, '.', '_', true)];
> font-fill: black;
> }
sld:
> <?xml version="1.0" encoding="UTF-8"?>
> <sld:UserStyle xmlns="http://www.opengis.net/sld"; xmlns:sld="
> http://www.opengis.
> <sld:Name>Default Styler</sld:Name>
> <sld:Title/>
> <sld:FeatureTypeStyle>
> <sld:Name>name</sld:Name>
> <sld:Rule>
> <sld:TextSymbolizer>
> <sld:Label>
> <ogc:PropertyName>PROP</ogc:PropertyName>
> </sld:Label>
> <sld:Fill>
> <sld:CssParameter
> name="fill">#000000</sld:CssParameter>
> </sld:Fill>
> </sld:TextSymbolizer>
> <sld:TextSymbolizer>
> <sld:Label>
> <ogc:Function name="strReplace">
> <ogc:PropertyName>PROP</ogc:PropertyName>
> <ogc:Literal>.</ogc:Literal>
> <ogc:Literal>_</ogc:Literal>
> <ogc:Literal>true</ogc:Literal>
> </ogc:Function>
> </sld:Label>
> <sld:Fill>
> <sld:CssParameter
> name="fill">#000000</sld:CssParameter>
> </sld:Fill>
> </sld:TextSymbolizer>
> </sld:Rule>
> </sld:FeatureTypeStyle>
> </sld:UserStyle>
Hope this helps (and I'll fix the docs in a bit.)

Simplify data backup and recovery for your virtual environment with vRanger.
Installation's a snap, and flexible recovery options mean your data is safe,
secure and there when you need it. Data protection magic?
Nope - It's vRanger. Get your free trial download today.
