Binary to ascii text

However, if you have two or more words, other codes can appear between the words, making them difficult to locate. The file below, even without any formatting, is huge, so we've removed large sections of it for clarity.

A major point we have to make here is that Word relies on the exact position of various aspects of the file being fixed, such as font tables, symbol tables and other internal references.

If these positions are changed e. Recovery may not be possible. An additional point to note is that the word 'Symbol' is stored in the Word document in Unicode format see below , so a text editor or text tool will not find it. Since this file contains mixed sections of ASCII and Unicode, it is crucial that the file positions are left unchanged.

ASCII is being replaced in many applications by Unicode , which uses 16 bits 2 bytes per character to represent non-Roman alphabets like Japanese, Chinese, and Cyrillic. A text editor or text tool won't find 'hello' in this file.

Now, to convert a binary file to a useful text form, you need to strip out all the binary characters - the formatting, control and other gobbledygook stuff. Plain Text File - hello. The return value is the converted line, including a newline char.

The newline is added because the original use case for this function was to feed it a series of 57 byte input lines to get output lines that conform to the MIME-base64 standard. Otherwise the output conforms to RFC Convert a block of quoted-printable data back to binary and return the binary data. If the optional argument header is present and true, underscores will be decoded as spaces. The return value is the converted line s. If the optional argument quotetabs is present and true, all tabs and spaces will be encoded.

If the optional argument istext is present and true, newlines are not encoded but trailing whitespace will be encoded. If the optional argument header is present and true, spaces will be encoded as underscores per RFC If the optional argument header is present and false, newline characters will be encoded as well; otherwise linefeed conversion might corrupt the binary data stream.

The string should contain a complete number of binary bytes, or in case of the last portion of the binhex4 data have the remaining bits zero. Perform RLE-decompression on the data, as per the binhex4 standard. The algorithm uses 0x90 after a byte as a repeat indicator, followed by a count. A count of 0 specifies a byte value of 0x The routine returns the decompressed data, unless data input data ends in an orphaned repeat indicator, in which case the Incomplete exception is raised.

The argument should already be RLE-coded, and have a length divisible by 3 except possibly the last fragment. Compute a bit CRC value of data , starting with an initial crc and returning the result. This CRC is used in the binhex4 format. Compute CRC, the bit checksum of data, starting with an initial crc. This is consistent with the ZIP file checksum. Since the algorithm is designed for use as a checksum algorithm, it is not suitable for use as a general hash algorithm. If you are only using the checksum in packed binary format this is not necessary as the return value is the correct 32bit binary representation regardless of sign.

Changed in version 2. In the past the value would be signed on some platforms and unsigned on others.
