If I am not wrong fonts in pdf have defined only widths. But I guess height
could be in font file or can be calculated from glyph vector
representation. Would not be enough to use font size as general height?

If you mean that you have PdfString with some text for example obtained in
this way from utf8:
PdfString text(reinterpret_cast<const pdf_utf8*>("Abc"));
And you have instance of PdfEncoding and PdfFont then in order to get
glyphs can be called
PdfEncoding::ConvertToEncoding( const PdfString & rString, const PdfFont*
pFont )
This is used in PdfFont::WriteStringToStream to generate hex encoded
parameter for Tj operator and is used for example in PdfPainter::DrawText.
But using PdfEncoding and PdfFont loaded from pdf has still some bugs:
