IMO the meaning is clear: searching for an sub*string* means an *exact*
match. Who wants case insensitive or otherwise inexact matches, has to
use specialized *text* functions.
Ambiguous character representations are a general problem with
characters, where e.g. line endings or whitespace can be represented in
different ways. The accent/umlaut composition is not a Unicode problem,
it occurs in all codepages.
