Unicode is "a character coding system designed to support the worldwide interchange, processing, and display of the written texts of the diverse languages and technical disciplines of the modern world." - The Unicode Standard
While there are fonts that will allow for IPA transcription required in your final project, Unicode is a more reliable method to use.
Using Unicode with a PC
Word 2007 (installed on Library PC's) suggests one of two ways to incorporate Unicode into documents:
1) Use the Unicode special character chart. To insert a Unicode character, type the character code, press ALT, and then press X.
For example, to type a dollar symbol ($), type 0024, press ALT, and then press X
2) Click Start, point to All Programs, then Accessories, then System Tools, and then click Character Map.
To select a character in the Character Map, click the character, click Select, click the right mouse button in your document where you want the character, and then click Paste.
Using Unicode with a MAC
To use Unicode on a MAC, you may either use the character viewer or, with unicode hex input selected from the settings>language & text >input sources menu, hold the option key and type the 4 digit code anywhere.
For assistance using Unicode, see "Where is My Character?" or consult with your professor.
