The CLIPBOARD selection is owned by a single program (or none) at a given time. Clipboard managers can steal the CLIPBOARD from the current owner so that, if the current owner terminates, the CLIPBOARD is not lost with it.

Maybe > 'text/plain;charset=utf-8' corresponds to a slightly different atom? Yes, each target is a different atom. “text/plain;charset=utf-8” is a mimetype, which modern applications often use. But “UTF8_STRING” is also widely supported. Older programs which don't know UTF-8 or mimetypes may use the “STRING” target and encode the selection into Latin-1 or ASCII.

No prob :) I recommend you to read the «§ Client Communication Events» section of the «Xlib - C Language Interface»[1], and the «§ Peer-to-Peer Communication by Means of Selections» section of the ICCCM[2]. The XDG has a few specifications on modern atoms, like the CLIPBOARD selection[3] and the UTF8_STRING target[4].
