To dump the ROS info, it needs "-n" option, as it is needed to dump /FontInfo
dictionary.
For the similarity with /FontInfo dumping, the syntax of the output is changed.
However, I didn't write a function named as Print_CIDFontInfo_Dictionary() but
wrote
a function named Print_ROS_From_Face(), because I didn't want to expose the
variables
to store registry, ordering, and supplement in its caller side, and ROS info
can be
found in non-CID-keyed font (in theoretically).
I tested it with both of raw CID-keyed font (like WadaGo-Bold), and
OpenType/CFF.

Thank you very much for positive comment - Indeed, yet I've not considered and
tested with real CID fonts! I should rework.
Showing a string type value after the numerical value might be strange.
In conventional PostScript CID fonts, ROS is usually identified as a string like Adobe-Japan1-4, where
"Adobe" is the registry name (stored as a string), "CNS1" is the ordering (stored as a
string), and "4" is the supplement level (stored as an integer), like:
/CIDSystemInfo 3 dict dup begin
/Registry (Adobe) def
/Ordering (Japan1) def
/Supplement 1 def
end def
In my experience, I've never seen a font including a hypen in the strings of
Registry and Ordering, so there might be few serious requirements to show R/O/S
separately.

ftdump is not a font debugger,
but it would be much more helpful if it can dump the ROS info from
OpenType/CFF.
I actually think that FreeType demos are the best font debugging tools out
there.
My preliminary patch is

Does such a feature in ftdump make sense? I hope to hear your comments.
This is great but please consider other output options. I am not familiar with
ROS. The CID fonts without charmaps might need this instead. Or is this a name?
It is a bit strange right after numeric metrics.
