# length

##### Function: length
  the length of a piece of text in unicode code points.  This is usually, but not
always, the same as the length of the text in user-perceived characters.

Examples:

length('hello')
-- Result: "5"

length("\u00e1") -- composed 'á'
-- Result: "1"

length("a\u0301") -- decomposed 'á'
-- Result: "2"
