Since you brought dogs' names up, how come you accent Pepe? There should be no accent, since it's a paroxytone (accent on the penultimate syllable) ending in a vowel. The same rule would apply if it ended in an n or s.

Well, for several reasons: I named him that after my uncle, the late great "Pepé", and that is how he spelled it. He, and everyone else that new him, pronounces the last "e" like the "e" in olé, pe-PAY with accent on the last "e". That is the way he explained it to me and the way
he spelled it and pronounced it. Also, people around here seem to be able to pronounce it right when I
do put the accent there. Otherwise it comes out like "Pee-pee"
So, I guess it comes down to personal reasons and personal preference in a country that can spell one name dozens of different ways, and have a dozen different ways to pronounce that same name. I guess it would be called individuality.
