(Just FYI - those characters I'm assuming are Greek letters, are showing up as garbled stuff here, sort of like the quotation marks on some posts.)

This began a few days ago. Thought it was just me. Anyone know what is causing the issue and how to prevent this?

Don’t know the root cause is, but the end result comes from copying and pasting. Jim and John are working on it.

You can’t prevent it, but you can correct it by deleting or backspacing over any strange characters that you notice in the preview before you post, and replacing them by typing whatever they were — a double quote, apostrophe, or dash.
