graphemes(s) -> iterator over substrings of s

Returns an iterator over substrings of s that correspond to the extended graphemes in the string, as defined by Unicode UAX #29. (Roughly, these are what users would perceive as single characters, even though they may contain more than one codepoint; for example a letter combined with an accent mark is a single grapheme.)


  1. Iterate over graphemes in a string:

    julia> for g in graphemes("Hello")

    This example iterates over each grapheme in the string "Hello" and prints them individually.

  2. Count the number of graphemes in a string:

    julia> count(graphemes("Julia is awesome!"))

    It counts the number of graphemes in the given string.

  3. Create an array of graphemes from a string:
    julia> arr = collect(graphemes("Julia"))
    5-element Array{String,1}:

    This example converts the graphemes in the string "Julia" into an array.

Common mistake example:

julia> graphemes("๐Ÿ‘จโ€๐Ÿ‘ฉโ€๐Ÿ‘งโ€๐Ÿ‘ฆ")
ERROR: MethodError: no method matching graphemes(::String)

In this example, the function graphemes does not support grapheme extraction from a string containing Unicode grapheme clusters. It is important to note that graphemes works with extended graphemes, not grapheme clusters.
