Abstract: Embodiments relate to a system, method and program product for performing code conversions. In one embodiment the method includes determining size of encoding space for a source file and a target file upon receipt of a code conversion request and generating a main conversion file upon determination that a target encoding space associated with said target file is smaller than a source encoding space associated with the source file. Subsequently an extension converted file is generated from the source file according to a pre-established mapping table of code conversion stored in a memory. The code conversion request is completed by using the main conversion file and said extension file together so that the source file does not need to be truncated in order to fit into the target conversion space.
