Converts a binary variant into a string.
BinaryToString ( expression [, flag = 1] )
expression | An expression to convert into a string. |
flag | [optional] Changes how the binary data is converted: $SB_ANSI (1) = binary data is ANSI (default) $SB_UTF16LE (2) = binary data is UTF16 Little Endian $SB_UTF16BE (3) = binary data is UTF16 Big Endian $SB_UTF8 (4) = binary data is UTF8 Constants are defined in StringConstants.au3. |
Success: | the string representation of the binary data. |
Failure: | an empty string and sets the @error flag to non-zero. |
@error: | 1 = Input string had zero length. 2 = Input string had an odd number of bytes but was supposed to be UTF16 (must contain an even number of bytes to be valid UTF16). |
Unlike String() which returns a hexadecimal representation of binary data, this function will assume the binary data is a string value and convert it appropriately.
See "Unicode Support" for a detailed description.

; $sOriginal - The original string before conversions.
; $dBinary - The original string after it has been converted to binary.
; $sConverted- The string after it has been converted to binary and then back to a string.
; $sConversionType - A human friendly name for the encoding type used for the conversion.
