am yisrael chai-
I assume some people will enjoy decoding more than being presented with the answer, so…
B’rshus “squeak”, here are two clues:
1) The code is a one-to-one character replacement.
2) The phrase “DR PEPPER” (no quotes, no period) is present in the first post.
My technique is to cut-and-paste the entire post into Notepad, then use “replace all” to change one character at a time. You can cut-and-paste one character at a time into the “Find What” window when replacing all, so you don’t actually have to type the funny characters.
