On case #4: select * from phone_records where caller_id= 11 or recipient_id = 11

The results header is screwed up, there is an extra 'id' column. At least on firefox.

"The vast majority of the population does not read or write any English in their day to day lives." This is doubtful: https://en.wikipedia.org/wiki/List_of_languages_by_total_num... While English speakers are not a majority, it is the most popular language. And one should also note that given English is the lingua franca of programming, I'd suspect that English as a second language is actually a majority for programmers. So any code that deals solely with programmers as users can easily just use standard ASCII as default, and never see any problems.

Fine dining generally has small portions, but there tend to be many courses and they really like to use meat so it actually adds up to a very substantial meal. If you ever go to one pace yourself, otherwise the last few courses will be quite unpleasant.
