Description:

OBSOLETE
    this class will vanish - its functionality has been replaced
    by the UnicodeString classes.

JISEncodedString represents 16bit strings encoded in JIS.
You need jis-encoded fonts on your display workstation, 
to display them (i.e. when switching to japanese ...).

Class protocol:

 defaultRomanCharacterValue

 romanTable

return a table to decode from roman ascii to 16 bit JIS.

WARNING: this is a temporary kludge for CJK characterSets and will be removed,
when the textViews always use unicode.

 encodeHalfWidthKatakana: aString

encode halfWidth katakana characters in aString.
Return the argument or a copy.

 initialize

initialize the class - private

Usage example(s):

JISEncodedString initialize

 jis7KanjiEscapeSequence

return the escape sequence used to switch to kanji in jis7 encoded strings.
This happens to be the same as ISO2022-JP's escape sequence.

 jis7RomanEscapeSequence

return the escape sequence used to switch to roman in jis7 encoded strings

 jisISO2022EscapeSequence

return the escape sequence used to switch to kanji in iso2022 encoded strings

 oldJis7KanjiEscapeSequence

return the escape sequence used to switch to kanji in old jis7 encoded strings

Instance protocol:

 encoding

return the strings encoding as a symbol.
Here, the constant symbol #jis is returned.

Examples:

JISEncodedString fromString:'hello world'

'hello world' decodeFrom:#jis7

<someStringWithJIS7Escapes> decodeFrom:#jis7
