Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.

[Q]: Question: Is there a word or phrase which describes "choice of misleading words", or the negation: "choice of non-misleading words"? The nearest phrases I can think of are linguistic deception, or controlled language, as in Nineteen Eighty-Four. For example, Richard Stallman actively opposes such misuse of language: I think it is ok for authors (please let's not call them creators, they are not gods) to ask for money for copies of their works (please let's not devalue these works by calling them content) in order to gain income (the term compensation falsely implies it is a matter of making up for some kind of damages). Another example is "credit" in banking, which just makes "debt" sound like a good thing. EDIT: The term may either refer to an individual's malicious use of misleading terminology, or to widely-accepted use of misleading terminology. The answers reflect this, but my question does not. 
Answer: George Orwell, in his novel Nineteen Eighty-Four, used the terms doublethink (the act of simultaneously accepting two mutually contradictory beliefs as correct) and Newspeak (a controlled language of restricted grammar and limited vocabulary, meant to limit the freedom of thought). These two have been combined to form the term doublespeak (frequently incorrectly attributed to Orwell's 1984) meaning "language that deliberately obscures, disguises, distorts, or reverses the meaning of words." More information and references at Wikipedia. The OP mentioned Nineteen Eighty-Four but not doublespeak.

[Q]: Question: I frequently encounter phrases like this: "It allows to apply these features to customisable sets of fonts". My question is whether this is proper English or not? In my mind, "it allows the application of ..." or "it allows one to apply ..." sound much better. I suspect that this is a Germanism (that would explain why I hear it so often), but it would be nice to know for sure.
