Chapter 9: Information Processing Techniques
Other Code Conversion Types
What you have learned already is enough to guide you through additional code conver-
sion types, so we haven’t covered every type of code conversion. Table 9-9 details how
to implement other conversions, and the integer values that are provided are in decimal
notation.
Code conversion matrixTable 9-9.
ISO-2022 Shift-JIS EUC Row-Cell
From
ISO-2022 n/a jis2sjis +128 −32
Shift-JIS sjis2jis n/a sjis2jis then +128 sjis2jis then −32
EUC −128 −128 then jis2sjis n/a −160
Row-Cell +32 +32 then jis2sjis +160 n/a
e string jis2sjis refers to the ISO-2022-JP to Shi-JIS conversion algorithm; likewise,
sjis2jis refers to the Shi-JIS to ISO-2022-JP conversion algorithm—both were described
in detail earlier in this chapter. e numbers prexed with either + (plus) or − (minus)
mean that you must add or subtract those amounts, in decimal, from both bytes. Also
note in the table how ISO-2022 is used as the middle ground for code conversion when
Shi-JIS encoding is involved—this does not mean such implementation is absolutely
necessary, but I nd it ecient to do so.
Java Programming Examples
e following sections illustrate, with example code, how trivial CJKV code conversion
can be when using the Java programming language. Specically, code conversion and text
stream handling techniques are provided.
