No. A hyphen can appear in an English word as well. For example:

There are the graphemes, œ and æ, which appeared first in medieval Latin to represent the Greek diphthong.
They are still used in everyday English (at least in the Queen's version), in words such as encyclopædia and fœtus. (At least they are usually written ae; those characters are not available on most keyboards).
I have noticed that Americans pronounce the first syllable of pædophile as one would pedestrian (suggesting pedophile - a lover of the feet?).
The reason they do this, presumably, is because they have lost contact with the diphthong.

And oh dear, Wikipedia has the same wretched shortcoming. Surely it should be Wikipædia, shouldn't it?
