We wonder whether there is a restriction such as maximum length of characters, pattern of characters to allow, etc.
Yes, lots. Please see the 'Theory' file, which discusses this.
One more question, is it really America/Costa_Rica or Japan a name or an ID?
America/Costa_Rica is a Zone, which has a name. Japan is a Link, which is an alias for Asia/Tokyo. This is discussed in the 'zic' man page.
