Why aren Greek letters sorting properly?
CINDEX normally treats Greek letters (in the symbol font) as their Roman letter counterparts (for example, the letter Ω (omega) is the same as the letter w). To make CINDEX sort a Greek letter as something other than its Roman counterpart, place the corresponding letter immediately beforeit in braces. For example, to sort omega (Ω) as ‘o’ you would place the letter ‘o’ beside it in braces, thus: {o}Ω. CINDEX uses text enclosed in braces when it alphabetizes entries, but hides that text when it displays or prints a formatted index.
