Integrated PDF uses a Font Manager, which allows for character-to-font mapping. It maintains a lookup table that maps from 2 byte Unicode character code to font. The table is initialized such that the first font that handles a specific character code is stored as the font for rendering that character code. By default, the table is initialized with Helvetica and CJK CID fonts (in this order: Simplified Chinese, Traditional Chinese, Japanese, Korean). The directory $SPLUNK_HOME/share/splunk/fonts is scanned for any additional true type fonts. These are added in between Helvetica and the default CJK fonts.
If you want to add another font, your Splunk admin (is that you?) should add the font to $SPLUNK_HOME/share/splunk/fonts. If it doesn't already exist, create the fonts directory.
The new font must be a truetype Unicode font.
