Do you pronounce foreign names with Spanish phonetics?

[Yoodle15]

I want to say the name of the English novelist "E.M Forster" in Spanish. How on earth do I pronounce his name using Spanish phonetics? Or should I pronounce it with English phonetics? Do I say "eh emeh" or "eee em" for the "E.M"?

Thanks in advance.

I also want to say the name "Eleanor" in a Spanish conversation.

For initials/letters, I would use the Spanish letter names when you are speaking Spanish.

With full names it's okay to use the usual English pronunciation until you and the person you're speaking with figure out which pronunciation of the name your listener actually uses or understands. If you have access to Spanish-language television or radio, you can try listening to international news programs to see how they pronounce the names of public figures from around the world.
