Combining marks are insufficient to break a string into graphemes

Q: So is a combining character sequence the same as a “character”?
A: That depends. For a programmer, a Unicode code point represents a single character (for exceptions, see below). For an end user, it may not. The better word for what end-users think of as characters is grapheme: a minimally distinctive unit of writing in the context of a particular writing system.
For example, å (A + COMBINING RING or A-RING) is a grapheme in the Danish writing system, while KA + VIRAMA + TA + VOWEL SIGN U is one in the Devanagari writing system. Graphemes are not necessarily combining character sequences, and combining character sequences are not necessarily graphemes. Moreover, there are a number of other cases where a user would not count “characters” the same way as a programmer would: where there are invisible characters such as the RIGHT-TO-LEFT MARK (RLM) used in BIDI, compatibility composites such as “Dz”, “ij”, or Roman numerals, and so on.
