How linux readerex differs from windows readerex in font usage

[HinTak]

• linux version: does not embed in either case, but use different non-embedded named fonts to draw, depending on whether simsun is present or not.

• windows version: does not draw text if font is missing. Texts silently missing if fonts are not present.

caj2pdf#63 works correctly in wine against the windows dlls if simsun is coped from windows into wine's font directory.

Went through all the dll/libs - the windows ordinal 216 is actually stable. But:

• dll from 2.3.3979.0 onwards can embed all fonts; 2.3.3978.0 is like the linux one, not embedding a few fonts.
• 32-bit windows is more reliable; 64-bit seems to have indeterminisms (repeat runs give slightly different outcome).
• versioning meaningless - 4 versions of 2.3.3982 gives 4 different outcome; the two 32-bit builds have different dependencies.
• the outcome differs by dependencies more than by versions (79-82 vs 82-83 differs ). And small version change in 78-79 gives major differences.
• in terms of font embedding, the linux version almost behaves like older windows ones.

About ordinal 216 - it works okay for issue-63 (other than font embedding) upto 2.0.3949.0, then 2.0.3920.0 breaks for this sample, and seems to not have jbig (just jbig2 + jpeg). 2.0.3684.0 and 2.0.3799.0 can read the jpeg cover only.
Older versions cannot read NH files.

Explained in code. If no font can be found, defaultFont is used to be an alternative to 报宋, following the definition below.

namespace GlobalParams
{
#if defined(OS_LINUX) || defined(OS_MACOS)
const char *defaultFontName = "HGHT_CNKI";
#elif defined(OS_WINDOWS)
const char *defaultFontName = "SimSun";
#endif
} // namespace GlobalParams

if (!strcmp(FontName, "报宋"))
{
	FontName = GlobalParams::defaultFontName;
	bFlag = 0;
}

Is that your code or cnki's? Seems incorrect, as per my early comment (linux version DOES try simsun):

linux version: does not embed in either case, but use different non-embedded named fonts to draw, depending on whether simsun is present or not.
