(Ignore the color, which is this web site taking my ASCII table for .tex source.)
Note that defaults may vary by script; see Khaled Hosny’s remarks at article.gmane.org/gmane.comp.tex.xetex/15187.
To judge from the manual at §28.0.12, there are also vertical kerning options, probably to be explained in §10.17.
Update
Since version 2.5c (2017/01/20), the fontspec manual also has a table; in version 2.6g (2017/11/09), it’s Table 2, on page 35.
EDIT: Based on the accepted answer above, the following answer, and comments, I have been able to solve my problem in detail. Thanks, all! Here is a MWE showing how it works.
% !TeX program = LuaLaTeX
% !TEX encoding = UTF-8
\documentclass{article}
\usepackage{fontspec} % required with LuaLaTeX
\setmainfont[
Ligatures=TeX,
Numbers=Proportional, % but cannot use Monospaced as below
]{Adobe Garamond Pro}
\newfontfamily{\myCustom}[
Ligatures=TeX,
]{RAcustom} % my own created opentype font
\newcommand\myFraktur{\addfontfeature{StylisticSet=1}} % only for \myCustom
\newcommand\myUncial{\addfontfeature{StylisticSet=2}} % only for \myCustom
\newcommand\myEmoticons{\addfontfeature{StylisticSet=3}} % only for \myCustom
\begin{document}
Hello {\myCustom world.} Here: {\myCustom\myEmoticons ^^^^46c7}
\end{document}
The above gives the expected output: "Hello " in AGaramondPro, "world." in RAcustom, "Here: " in AGaramondPro, and Unicode 46c7 (which would ordinarily be an Asian Han character) in RAcustom opentype feature ss03, which is a grin emoticon. Factoid: the Han character means "grin." I didn't want to use the full Unicode range beyond the BMP.
Thank you thank you thank you!
