Can you describe these?

Ant the wrong one! The TeX encodings are scrap. At least for use outside of TeX. The character N-ARY SUMMATION lives in Unicode at the point U+2211 (the number is hex; in decimal it's 8721, in UTF-8 it's 0xE28891, in XHTML it's ∑ or ∑).

The TeX Gyre fonts are Unicode encoded. Because they are meant to be used by Mac OS X applications. And Mac OS X (and also the last editions of classical Mac OS) uses Unicode. So they need to have a natural encoding. (Not every application applies a CMap-ing.)

In Mac OS X you can use its "Character Palette", which has to be enabled in System Preferences: Language & Text -> Input Sources: √ Keyboard & Character Viewer + √ Show Input menu in menu bar – in Mac OS X 10.6. In younger instances I've seen changes.

You can also use UnicodeChecker from http://earthlingsoft.net.
