() -> ::Array[::String]

() { (::String grapheme_cluter) -> void } -> self

grapheme_clusters → array_of_grapheme_clusters

static VALUE
rb_str_grapheme_clusters(VALUE str)
{
    VALUE ary = WANTARRAY("grapheme_clusters", rb_str_strlen(str));
    return rb_str_enumerate_grapheme_clusters(str, ary);
}

Returns an array of the grapheme clusters in self (see Unicode Grapheme Cluster Boundaries):

Example

s = "ä-pqr-b̈-xyz-c̈"
s.size                   # => 16
s.bytesize               # => 19
s.grapheme_clusters.size # => 13
s.grapheme_clusters
# => ["ä", "-", "p", "q", "r", "-", "b̈", "-", "x", "y", "z", "-", "c̈"]

Details:

Example

s = "ä"
s.grapheme_clusters             # => ["ä"]           # One grapheme cluster.
s.bytes                         # => [97, 204, 136]  # Three bytes.
s.chars                         # => ["a", "̈"]       # Two characters.
s.chars.map {|char| char.ord }  # => [97, 776]       # Their values.
