strLength(attribute) does compute the number of chars. Yet I'm not sure it's what you want, since the rendered width of "MMMM" and "||||" is different. Unfortunately afaik we do not have a function that does return actual rendered width and height. In fact, to provide a proper answer to this problem, a new element similar to halo should be added to TextSymbolizer, since it has the same function as a halo, that is, make text easier to read... well, it could even be a Halo new attribute. Both would require changing published API in 2.2.x, so I'm not sure we're speaking about a quick change (I doubt it... everything handling styles would need to be changed as an effect, parsers, encoders, implementations of the interface...)
