This version does not contain embedded fonts unlike 1.4.2.
It uses standard Android fonts to render PDF docs.
The release version will have ability to use various font packs.

At the moment we have hardcoded font names:

char* ext_font_Courier = "/sdcard/.org.ebookdroid/fonts/FreeMono.ttf";
char* ext_font_CourierBold = "/sdcard/.org.ebookdroid/fonts/FreeMonoBold.ttf";
char* ext_font_CourierOblique = 
"/sdcard/.org.ebookdroid/fonts/FreeMonoOblique.ttf";
char* ext_font_CourierBoldOblique = 
"/sdcard/.org.ebookdroid/fonts/FreeMonoBoldOblique.ttf";
char* ext_font_Helvetica = "/sdcard/.org.ebookdroid/fonts/FreeSans.ttf";
char* ext_font_HelveticaBold = "/sdcard/.org.ebookdroid/fonts/FreeSansBold.ttf";
char* ext_font_HelveticaOblique = 
"/sdcard/.org.ebookdroid/fonts/FreeSansOblique.ttf";
char* ext_font_HelveticaBoldOblique = 
"/sdcard/.org.ebookdroid/fonts/FreeSans.ttf";
char* ext_font_TimesRoman = "/sdcard/.org.ebookdroid/fonts/FreeSerif.ttf";
char* ext_font_TimesBold = "/sdcard/.org.ebookdroid/fonts/FreeSerifBold.ttf";
char* ext_font_TimesItalic = 
"/sdcard/.org.ebookdroid/fonts/FreeSerifItalic.ttf";
char* ext_font_TimesBoldItalic = 
"/sdcard/.org.ebookdroid/fonts/FreeSerifBoldItalic.ttf";
char* ext_font_Symbol = "/sdcard/.org.ebookdroid/fonts/StandardSymL.cff";
char* ext_font_ZapfDingbats = "/sdcard/.org.ebookdroid/fonts/Dingbats.cff";

"This version does not contain embedded fonts unlike 1.4.2"

Does this mean that the problem is caused by the new feasure "PDF built-in
fonts removed".

why add a  features that compromise rendering quality.

I have a feeling that rendering quality in the new version is worse than
that of old.

ensuring that pages are rendered at publication quality is a function that
should never be compromised.

Embedded fonts in MuPDF do not support full glyph range, for example it misses 
cyrillic and east europe glyphs. So, we decided to use external fonts with full 
glyph range.

All questions about rendering quality address to MuPDF team.
