Mac OS 10.2 and above provides complete Unicode support and CLANX is now able to use this support. Apple provides input methods for all major languages, including right-to-left support for Hebrew, Thai, and Arabic. To use Unicode on OS X, follow these instructions:

• Install a recent copy of CLANXu - the Unicode version of CLAN for Mac.
• Install one or more Unicode fonts in /Library/Fonts/. See below for suggested Unicode fonts.
• Open a new file. If you have installed ArialUnicode, it will be selected as the default font. If you want to use some other Unicode font instead, then you can pull down the "Fonts" menu and select the font you wish to use.
• If you need to work with older non-UTF CHAT files, you can convert them to UTF format using CLAN's CP2UTF program.

• A good all-around Unicode font is Arial Unicode, which comes with Office Professional. Most universities install Arial Unicode on all of their Windows computers. You can also purchase Arial Unicode from ascenderfonts.com ($99 for a 5-user license). Make sure you purchase Arial Unicode and not just Arial.
• CA analysts, or Mac users who cannot locate or afford ArialUnicode and do not want to use the CERG font, can install our own fixed-width Unicode CAfont. We provide this as a free font in accord with distribution permitted by Bitstream.
• For Chinese, you can use the freeware CERG Chinese Font which also provides Roman characters and many symbols. For other Asian languages, Unicode fonts come pre-installed.
• If you want to use IPA characters, install the IPAKeys program provided by Tim Flood. You can also get the free CharisSIL proportional-width fonts designed specifically for IPA characters.
