Standard Korean fonts have no bold or italic variants.

Despite that, Adobe Acrobat can automatically apply the bold facing for
*any* font if the font name has a special form, namely '<fontname>, Bold'.

Earlier versions of XEP takes font names from 'font name' entry in the font
configuration file and passes it to PDF file untouched.
So PDF documents created by XEP 3.6 or earlier can be displayed with bold
Korean characters (in Acrobat only).

Since version 3.7, XEP relies only on the actual font face defined by font
authors (that is on a real font data read from a 'ttf' file), rather then on
the 'font name' entry in the font configuration file. Therefore the only way
to display bold characters properly is to supply font with bold-faced
outlines.

This is a correct behavior; it is defined by font selection strategy used by
default.
Setting 'font-selection-strategy="character-by-character"' will give you the
desired visual result.

Subject: [xep-support] Bold or italic Korean font does not work

Hi,

we use XEP 3.84 server license.

For Korean characters in FO document content we use the font
"AdobeMyungjoStd-Medium-Acro" taken from Acrobat Reader 6, Korean version.

According to the XEP documentation we have made the binary font file
available by copying into XEPs font directory and registered it by adding a
new font descriptor to ".../etc/fonts.xml". We have added the font family
name (alias) to the attribute "font-family" of the element "fo-root" in our
FO documents. This works well.

Unfortunately we are not able to make this font show an italic font style or
bold font weight. For a standard font like "Helvetica" this works.

We have used the following entries in "fonts.xml"

The first entry works whereas the second does not. To activate the second,
bold faced, font we added the alias "AdobeMyungjoStd-Bold" to the list of
font-families and used font-weight="bold" to format.

We have following questions:
1. Did we use the correct syntax for including the second font "variant"?
(We created this comparing to the fonts which were already included in
fonts.xml.)
2. Does anyone know if the font we use is capable of font weight bold or
font style italic at all?
3. Can anyone provide an alternative solution?

Using the scenario above, if we have a mixture of Latin an Korean characters
in sequence the XEP output will apply (e.g.) font weight bold to the first
sequence of Latin characters until it comes across the first Korean
characters and does not switch back to font weight bold for the rest of the
Latin characters. Is this a known problem? If so is there any fix for it?

Best regards
