Hello,
yes currently the libwps' filter does not support shift-JIS, one solution is to
choose the old filter in the filter's dialog "Lotus-1-2-3" which must still
exists:-~

After, it is possible to add support shift-JIS encoding in libwps but I will
need a file with contains some SJIS characters and its corresponding screenshot
(to check that the conversion is valid).

If I must compare the old and the libwps's filter: clearly the libwps's filter
supports less encodings while it must be able to open password protected files,
retrieve more styles, ... 

Note: There is also a big problem in the old filter ; in fact, a 123 file can
contain (and does contain) many sub streams which can be stored in one
consecutive block or decomposed in many sub block. The list of streams is
stored at the end of the 123 file, the file begins with the main stream which
contains the sheet's data, styles, ... (which explains why the old filter often
works) ; but if a chart, a picture is inserted in a spreadsheet, the content of
the file will become:
  main Zone (part 1)
  picture Zone
  main Zone (part 2)
  ...
  metadata Zone
  file structure (list of stream)
( so the old parser will begin to parse the main Zone (part 1) and will
probably stop somewhere in the picture zone)
