PDF font multibyte character display.

The display of multibyte characters in the print to PDF mode has some limitations.
The languages for which these limitations apply, are the following:

- Arabic
- Greek
- Hebrew
- Russian
- Turkish
- Polish
- Baltic
- Chinese
- Korean
- Japanese
- other languages that do not display well

If you want to show characters from these languages correctly in your PDF file, there are 2 ways of achieving this:


1. Use arialuni.ttf

The ttf-files arialuni.ttf and/or arial.ttf font files must be present on a certain location. These font files are 
Windows TrueType fonts, which usually are present on a Windows environment in the directory $WINDIR/Fonts. 
If it is not present, it must be installed to this location from the Windows installation CD.

These fonts will also work on any other environment if they are placed in the proper directory.
For the following environments this directory is:
For Solaris: /usr/openwin/lib/X11/fonts/TrueType/
For Linux:   /usr/lib/X11/fonts/TrueType/
For Unix:    /usr/share/fonts/default/TrueType/

If the converter cannot determine the environment, the converter tries the Unix directory. (In some cases it was needed to put ttf-files in the 
Unix-directory for Solaris.)

This font directory can also be set in PDF.properties by adding ttf-font-path property. On Windows systems make sure the path-separator is / or \\.
For example: ttf-font-path = C:/ttf-files/

If you place the arialuni.ttf and/or arial.ttf file in this directory (for instance by copying it from a Windows system),
the characters from the given languages will display correctly.

For monospaced reports you also need the cour.ttf file in the directory (mentioned above) to ensure an optimal layout.

If the cour.ttf file is not present, all the characters will show up correctly, but the layout of different lines in the pdf file
with respect to each other may not be optimal.


2. Use a directory containing ttf and/or otf files

The font that supports the most languages is probably the Noto-font made by Google. The converter will support
this font if the following steps are executed:

	1. download the noto-font from https://www.google.com/get/noto/
	2. store NotoSans*-Regular.ttf and NotoSans*-Regular.otf in a local directory, for example c:/fonts/notosans.
	3. add "default-proportional-font=c:/fonts/notosans/" to PDF.properties

The same procedure will also work for other fonts. Please make sure this directory does not contain multiple
different fonts, but only the different internationalized files for a single font.
