CompareString() versus AnsiCompareString()


What is the difference between CompareString() and AnsiCompareString()?

Stefan Hoffmeister explains:

Some languages have characters outside of the ASCII character set; these two strings will compare differently depending on whether you use CompareString or AnsiCompareString:


'' is a German character, and with AnsiCompareString, the correct lexical order returned would be different:

AnsiCompareString observes the lexical order of your current locale - while CompareString only looks at the bits and bytes of the data. If you want to compare 'text', then do use AnsiCompareString. If you want to compare ASCII-only text (or just bytes), then use CompareString.
