I'm looking for a utility or an InDesign script or plug-in that would allow me to place every character of a font in a text box in InDesign. That includes all of the upper/expert character positions on OpenType fonts. Ideally, I'd like to display the character position number, and the character name (if the character has a name) followed by the character. If it were in a table, all the better. I'm looking to do this largely for troubleshooting purposes, to confirm what characters output correctly when the file is printed or exported.

Since we're dealing with some older PostScript fonts that were converted to OpenType and some new OpenType fonts, the number of characters in the fonts is going to vary. I imagine that would present some scripting challenges.

If the utility is external to InDesign but allows the functionality I need, such that I can copy and paste from it into InDesign, that would suit my purposes fine.

Any ideas?

Thanks.
