I think X-Symbol installs its own set of fonts with an encoding of their own. I suspect those more likely or not to be hand-created (or at least hand-corrected) on a per-pixel base rather than by some computational tracing process from a vectorized description. I see this effect a lot in musical instruments: mechanical processes and milling precision have improved so much in the last half century that there seems to be little point in putting in additional manual labor. But it was actually the manual labor that created a coherent whole from too crudely mechanically preprocessed raw materials. When the raw result was falling short by 10%, omitting the finishing work was not much of an option. If it falls short by 1%, why bother? To get back to the issue in question: In particular for obscure code points nobody is likely to be using? The code points in X-Symbol's own fonts, in contrast, are known to be exercised a lot, so correspondingly more care went into them. -- David Kastrup
