Nitpick: Those are Unicode characters, not UTF characters. UTF is just a family of encoding schemes for Unicode codepoints. (Bonus nitpick: Also, those are not characters, they're glyphs. The term "character" is so indefinable that the Unicode standard, to my knowledge, never uses the term.)

The rest of my comment quotes from the spec, from the section "Characters, Not Glyphs" > The Unicode Standard draws a distinction between characters and glyphs. Characters are the abstract representations of the smallest components of written language that have semantic value. They represent primarily, but not exclusively, the letters, punctuation, and other signs that constitute natural language text and technical notation. The letters used in natural language text are grouped into scripts—sets of letters that are used together in writing languages. Letters in different scripts, even when they correspond either semantically or graphically, are represented in Unicode by distinct characters. This is true even in those instances where they correspond in semantics, pronunciation, or appearance. > Characters are represented by code points that reside only in a memory representation, as strings in memory, on disk, or in data transmission. The Unicode Standard deals only with character codes. > Glyphs represent the shapes that characters can have when they are rendered or displayed. In contrast to characters, glyphs appear on the screen or paper as particular representations of one or more characters. A repertoire of glyphs makes up a font. Glyph shape and methods of identifying and selecting glyphs are the responsibility of individual font vendors and of appropriate standards and are not part of the Unicode Standard. > Various relationships may exist between char acter and glyph: a single glyph may correspond to a single character or to a number of characters, or multiple glyphs may result from a single character.
