False. Many characters can be represented by different
sequences of codepoints.
For instance, ê can be ê as one codepoint or ^ as a modifier
followed by e. ö is
one such character.
There are 3 levels of Unicode support. What Andrei is talking
about is Level 1.

I wonder what rationale there is for Unicode to have two
different sequences of codepoints be treated as the same. It's
madness.
To be able to convert back and forth from/to unicode in a
lossless manner.
