    Open Live Script

    Convert a string to bytes using the latin1 encoding scheme. 

    unicodestr = "hello";
bytes = unicode2native(unicodestr,"UTF-16")
    bytes = 1×12 uint8 row vector

   255   254   104     0   101     0   108     0   108     0   111     0

    Input Arguments

    collapse all

    Unicode text, specified as a string scalar or character vector.

    Unicode encoding scheme, specified as a string scalar or character vector containing the encoding scheme name. Some example encoding schemes are: 'UTF-8', 'latin1', 'US-ASCII', or 'Shift_JIS'. This function accepts encoding schemes defined by the International Components for Unicode (ICU) libraries, for more information, see Conversion in the ICU documentation.

    Output Arguments

    collapse all

    Bytes, returned as a uint8 vector where each element is in the range [0,255].

    Data Types: uint8

    Tips

    • The default encoding scheme might not match the encoding scheme of text read from a file.
