Absolutely any Unicode or ANSI character can be used as part of symbol name. There only some limitations in form of symbol declaration.
 
1. Direct symbol declaration (in form of quote or ') must not be started from control codes (first 32 characters), numbers and @. Next characters in symbol must not be control code neither @.
 
2. Direct symbol declaration (in form of ||) must not contain character |.
 
3. Functional symbol creation (in form of string->symbol) have no any limitations.
