Going deep in overlayer DrawText problem, I found that the font list in my system, got from OSD_FontMgr, is this one :
book
demibold

light

Which, IMHO, has nothing to do with true font names.....
My system is Ubuntu Linux 64 bit.
Being not able to find any font, then, the overlayer DrawText grabs the first available font with first available size, which is obviously wrong.

Digging a bit more, in
void OSD_FontMgr::InitFontDataBase() {
replacing a line :
// In current implementation use fonts with ISO-8859-1 coding page.
// OCCT not give to manage coding page by means of programm interface.
// TODO: make high level interface for
// choosing necessary coding page.
TCollection_AsciiString aXLFD;
---> HERE Standard_Integer leftXLFD = aLine.SearchFromEnd(" ");
Standard_Integer rightXLFD = aLine.Length();
if( leftXLFD && rightXLFD )
aXLFD.AssignCat(aLine.SubString( leftXLFD + 1, rightXLFD ) );
with
// In current implementation use fonts with ISO-8859-1 coding page.
// OCCT not give to manage coding page by means of programm interface.
// TODO: make high level interface for
// choosing necessary coding page.
TCollection_AsciiString aXLFD;
--->HERE Standard_Integer leftXLFD = aLine.Search(" -");
Standard_Integer rightXLFD = aLine.Length();
if( leftXLFD && rightXLFD )
aXLFD.AssignCat(aLine.SubString( leftXLFD + 1, rightXLFD ) );
Does the trick and makes OSD grab the right font names.
That one solves all my overlayer DrawText problems.

I don't know why some are repeated; I guess they're variants of faces.
