Examples of Unicode String comparisons compared to the .NET framework default

I'm looking for some examples of how and when smart people do a Unicode comparison of strings, versus the framework default.

Since many people don't work with strings from other cultures, here are a few interesting comparison examples I found.

  1. .ToUpper()
    • The lowercase Turkish 'i' converts to an uppercase İ (U+0130)
  2. Equals
    • The uppercase version of the Turkish example above
  3. Comparing equality for the last word in a sentence
    • Hebrew treats the last letter in a sentence differently then how it would be represented in Arabic
  4. ... other examples ...

Question
What comparisons are common in the Unicode world? (feel free to expand on the language examples)

What situations should I use (or not use) culture insensitive comparisons? This seems to boil down to either a "linguistic", or a "non-linguistic/(binary)" operation.

I'm particularly interested how this would affect Chinese and other eastern languages.
