This is a follow-up issue to internal #110298#:

From #110298#:
"as seen by HDU an me, some Sun fonts are known as e.g. SunSans-Regular (with an
hyphen instead of a blank in its name); in this case the name gets stripped to
"sansregular" and in a second step to "" an empty string. Hence the font
matching only relies on the attrbutes of the font name, which lead on a "fedora
core 2" to an b&h lucida bitmap font to be matched to.
This problem is currently workarounded by several new "SubstFonts" sections in
VCL.xcu for "sansregular" , "sansdemi" , "sansheavy" , "sansbold" , "sansitalic"
and so on."

US->HDU: you volunteered for a real/better solution.
