English teacher, technologist from Idaho but living in United Arab Emirates. Came up with the idea for the Simplified English wikipedia.
I noticed you removed the curly quotes and em dashes from Sapir-Whorf hypothesis. I don't have a problem with that and won't change it back, but since they were encoded correctly (they weren't the incorrect Windows-specific characters that some people put here), the fact that you were not able to see them correctly is a bug in your browser that you should look into. I would, in general, prefer that these particular characters be allowed in Wikipedia. See Wiki special characters for more details. --LDC
