At the linguistics conference, there were no / not / non- native speakers of Esperanto. They're all grammatically "valid", but they all mean different things - and pragmatically / idiomatically, only the no version is likely to be used.
25 Does "non-" prefixed to a two word phrase permit another hyphen before the second word? If I want to refer to an entity which is defined as the negation of another entity by attaching "non-" it seems strange to attach the "non-" only to the first word when the second one is really the word naming the entity. For example, non-control freak
"Non-" is defined as "a prefix meaning 'not,' freely used as an English formative, usually with a simple negative force as implying mere negation or absence of something (rather than the opposite or reverse of it, as often expressed by un-).
Except "non" is not an English word, it is a prefix of Latin origin. Which is why American style manuals will always ask you to merge it with the subsequent word, without a hyphen. British rules differ, and the "non-" construction is frequently found in the literature.

A person who is accustomed to that framework may feel the need to use the phrase ‘non-zero probability’ or ‘non-zero chance’ to make it clear that whatever is talked about is not impossible. To a person who is not accustomed to it, such a phrase seems strange, just like the non-zero speed in the above example.
The usage of a non-breaking space is explained in a Wikipedia article under Non-breaking spaces and Controlling line breaks and below in items 1 and 5: It is advisable to use a non-breaking space (also known as a hard space) to prevent the end-of-line displacement of elements that would be awkward at the beginning of a new line: in expressions in which figures and abbreviations (or symbols ...
non: nonviolent, nonevent, nonnegotiable, but non-beer-drinking Other style guides differ, and of course personal preferences are all over the map; but the coverage in Oxford and Chicago strongly suggests that UK usage is split (or indifferent) as between non-stop and nonstop, while U.S. usage definitely favors the latter.
To record and summarize the discussion in the comments, while the OED mostly uses the hyphen, many other dictionaries don't, and the ngrams show higher non-hyphenated usage than hyphenated.
