As shown in the attachment below, FT-2.3.4 seems to have problems to fake bold characters in Legedum's lowercase and uppercase acute accented letters. Just in case it helps, FT uses autohinter.

The FreeType emboldener is sensitive to errors in contour orientations, i.e., the wrong orientation would inverse the direction of emboldening, making some parts thinner. There is no way to diagnose the orientation errors in FreeType currently.
In fact, you can consider these emboldening artifacts as a diagnostic of the problem fonts. :) This is a feature, rather than bug.
