BinaryFormat.Text

Syntax

BinaryFormat.Text(length as any, optional encoding as nullable number) as function 

About

Returns a binary format that reads a text value. The length specifies the number of bytes to decode, or the binary format of the length that precedes the text. The optional encoding value specifies the encoding of the text. If the encoding is not specified, then the encoding is determined from the Unicode byte order marks. If no byte order marks are present, then TextEncoding.Utf8 is used.

Example 1

Decode two bytes as ASCII text.

Usage

let
    binaryData = #binary({65, 66, 67}),
    textFormat = BinaryFormat.Text(2, TextEncoding.Ascii)
in
    textFormat(binaryData)

Output

"AB"

Example 2

Decode ASCII text where the length of the text in bytes appears before the text as a byte.

Usage

let
    binaryData = #binary({2, 65, 66}),
    textFormat = BinaryFormat.Text(
        BinaryFormat.Byte,
        TextEncoding.Ascii
    )
in
    textFormat(binaryData)

Output

"AB"
