SYLK (Symbolic Link) format- this text format is used to exchange data between applications, specifically spreadsheets. Files of SYLK have «.slk» extension. Microsoft does not publish a SYLK specification, therefore work with this format in different applications can be different.
Notice: A SYLK file can be written in Unicode and read by some applications but anyway many applications which do support Unicode writes SYLK files into ANSI but not Unicode. Therefore, symbols which do not have representation in the system code page will be written as ('?') symbols.
