RAD PDF - Interactive Demonstrations

RAD PDF supports Unicode characters, but by default, Windows may not provide the fonts necessary to output proper PDF files. For example, the version of Arial which ships with Windows does not support most Chinese, Japanese, and Korean (CJK) characters. If you install Arial Unicode MS, RAD PDF will automatically detect it and use it to provide support for these other character sets. Arial Unicode MS must be licensed for use on a server (which this server is), so you may wish to consider other fonts. In this example, we demonstrate how to setup RAD PDF to also use Microsoft JhengHei (for Traditional Chinese), MS PGothic (for Japanese), and Malgun Gothic (for Korean) which are pre-installed on most version of Windows. We use the open source font Noto as a fallback web font for clients which don't have the font installed.
