Since titles and legends are not really used in the preview outputs, I'm guessing you're mostly referring to map labelling/symbology, right? Then, "when translation is possible" is the tricky bit, it would require analyzing the contents of the SLD, as it's all based on dynamic functions <https://docs.geoserver.org/stable/en/user/styling/sld/language.html>, and make a guess based on some common usage patterns. (e.g., using the language function inside recode, but it could also be using a tree of if_then_else for example). As simpler alternative, just blinding add the language=<id> in the request based on the combo box, and let the style do its thing, hoping it was set up to produce some output regardless of the choice being made. For example, look at this, taken from the <https://docs.geoserver.org/stable/en/user/styling/sld/language.html#using-the-language-function> documentation <https://docs.geoserver.org/stable/en/user/styling/sld/language.html#using-the-language-function> : <TextSymbolizer> <Label> <ogc:Function name="Recode"> <ogc:Function name="language"/> <ogc:Literal/> <ogc:PropertyName>name_default</ogc:PropertyName> <ogc:Literal>en</ogc:Literal> <ogc:PropertyName>name_en</ogc:PropertyName> <ogc:Literal>it</ogc:Literal> <ogc:PropertyName>name_it</ogc:PropertyName> <ogc:Literal>fr</ogc:Literal> <ogc:PropertyName>name_fr</ogc:PropertyName> </ogc:Function> </Label> <Fill> <CssParameter name="fill">#000000</CssParameter> </Fill></TextSymbolizer> The above SLD generates labels for cases with no LANGUAGE parameter, and for en, it, fr values. If you input something else (e.g. ger/de) then you'd get no label at all. Figuring out if the SLD has general defaults seems roughly as hard as coming up with a list of languages it would support.
