Actually, N is encoded with as a codepoint for N followed by a codepoint
for 'combining caron'. These 'combining codepoints' modify the character
suggested by the previous codepoint, more or less.

Unicode is intended to encode text as character-streams, rather than
glyphs, but it certainly does not in general encode one character per
codepoint.

N-caron is a character.
Unicode encodes characters.
Unicode encodes N-caron as a sequence of two codepoints.

Now some characters, such as 'M', can be encoded using one codepoint.
Some, such as '' (a-grave), can be encoded in several ways.

Correct.

>CH is a character is in Slovak.

Correct. Unicode encodes that Slovak character as U+0043 U+0048.
