com.lowagie.text.pdf.TrueTypeFontUnicode
- All Implemented Interfaces:
Comparator
Represents a True Type font with Unicode encoding. All the character in the font can be used directly by using the
encoding Identity-H or Identity-V. This is the only way to represent some character sets such as Thai.
