what is 'encoding default' in dataset?

The addition ENCODING defines how the characters are represented in the text file. When writing in a text file, the content of a data object is converted to the representation entered after ENCODING, and transferred to the file. If the data type is character-type and flat, trailing blanks are cut off. In the data type string, trailing blanks are not cut off. The end-of-line marking of the relevant platform is applied to the transferred data by default. When reading from a text file, the content of the file is read until the next end-of-line marking, converted from the format specified after ENCODING into the current character format, and transferred to a data object.

The end-of-line marking depends on the operating system of the application server. In the MS Windows operating systems, the markings "CRLF" and " LF" are possible, while under Unix, only "LF" is used. If, when using Windows, an existing file is opened without the TYPE addition (see os_addition), the first end-of-line marking is found and used for the whole file. If a new file is created without the TYPE addition, the content of the profile parameter abap/NTfmode is used. If the profile parameter is not set, "CRLF" is used. If a file with the TYPE addition is opened and a valid value is contained in attr, this value is used.

In Unicode programs, only the content of character-type data objects can be transferred to text files and read from text files. The addition ENCODING must be specified in Unicode programs, and can only be omitted in non-Unicode programs.

The additions after ENCODING determine in which character representation the content of the file is handled.

DEFAULT

In a Unicode system, the designation DEFAULT corresponds to the designation UTF-8, and the designation NON-UNICODE in a non-Unicode system.

UTF-8

The characters in the file are handled according to the Unicode character representation UTF-8.

NON-UNICODE

In a non-Unicode system, the data is read or written without being converted. In a Unicode system,the characters in the file are handled according to the non-Unicode-codepage that would be assigned to the current text environment according to the database table TCP0C, at the time of reading or writing in a non-Unicode system.

If the addition ENCODING is not specified in non-Unicode programs, the addition NON-UNICODE is used implicitly.
