# isGraphemeExtend

A Boolean value indicating whether the scalar is a grapheme extender.

```
var isGraphemeExtend: Bool { get }
```

## Discussion

A grapheme extender can be thought of primarily as a non-spacing glyph
that is applied above or below another glyph. For example, when the
character `é` is represented in its decomposed form, the grapheme base is
“e” (U+0065 LATIN SMALL LETTER E) and it is followed by a single grapheme
extender, U+0301 COMBINING ACUTE ACCENT.

The set of scalars for which `isGraphemeExtend` is `true` is disjoint by
definition from the set for which `isGraphemeBase` is `true`.

This property corresponds to the “Grapheme_Extend” and the
“Other_Grapheme_Extend” properties in the
[Unicode Standard](http://www.unicode.org/versions/latest/).
