utf8-byte-length
Get the utf8 byte length of a string, taking into account multi-byte characters and surrogate pairs.
By default, this module defers to Buffer.byteLength
. A browser
implementation is also provided that doesn't use Buffer.byteLength
minimize build size.
Example
var getLength = require("utf8-byte-length")
console.log(truncate("a☃", 2)) // a = 1 byte, ☃ = 3 bytes
// -> 4
API
var getLength = require("utf8-byte-length")
When using browserify or webpack, this automatically resolves to an
implementation that does not use Buffer.byteLength
.
getLength(string)
Returns the byte length of string
. Throws an error if string
is not
a string.
