Entities Find & Replace IDCS2

Hi,

I want to find & replace symbols like alpha, beta, etc. The main problem I am facing due to fonts. Some time these characters is owing symbol font, & some time Times New Roman, etc. (many fonts).

Is there anyway to search these entities without mentioning the fonts. I want to develop a script to find and replace the fonts to unicode value.

Please share the ideas, it will really help me. And really will great appreciable.

I am using InDesign CS2.

Thanks

If these are characters from the standard 256 character set, you should be able to reference them by ASCII number.
