ABAP Keyword Documentation → ABAP − Reference → Processing Internal Data → Assignments → Assignment and Conversion Rules →System Classes for Converting Character Sets and Number Formats
The system classes described below enable the conversion of text data between different code pages and of numeric data between different number representations.
Among other things, these classes are a (possible) replacement for the language elements TRANSLATE ... CODE PAGE ... and TRANSLATE ... NUMBER FORMAT ..., the use of which is forbidden in Unicode programs.
Data that is not available in ABAP format (that is, text data that is not in the system code page format, or numerical data that is not in the byte order used on the current application server) can be saved in binary form in an x field or in an xstring.
This is done using the following classes:
Note
The class CL_ABAP_CODEPAGE wraps the methods above to make it easier to handle code pages when processing character and byte strings.
