---Purpose: This class provides functions used to convert a non-ASCII C string
|
|
-- given in ANSI, EUC, GB or SJIS format, to a
|
|
-- Unicode string of extended characters, and vice versa.
|

|
---Purpose: Converts non-ASCII CString <fromstr> in SJIS format
|
|
-- to Unicode ExtendedString <tostr>.

|
|
|
|
|
ConvertEUCToUnicode(myclass;

---Purpose: Converts Unicode ExtendedString <fromstr> to non-ASCII
|
|
-- CString <tostr> in SJIS format, limited to <maxsize>
|
|
-- characters. To translate the whole <fromstr>, use more
|
|

-- <maxsize> has not been reached before end of conversion.

---Purpose: Converts Unicode ExtendedString <fromstr> to non-ASCII

|
|
-- functions ConvertFormatToUnicode and
|
|
-- ConvertUnicodeToFormat to convert the strings.

|
|
---Purpose: Returns the current conversion format (either

|
-- advance with the SetFormat function.

|
---Purpose: Converts the non-ASCII C string fromstr to the

-- Unicode string of extended characters tostr.
|
|
-- fromstr is translated according to the format

---Purpose: Converts the Unicode string of extended

|
-- characters fromstr to the non-ASCII C string
|
|
-- tostr according to the format (either ANSI, EUC,
|
|
-- GB or SJIS) returned by the function GetFormat.
|
|
-- maxsize limits the size of the string tostr to a
|
|
-- maximum number of characters. You need more
|
|
-- than twice the length of the string fromstr to
|
|
-- complete the conversion.
|
|
-- The function returns true if conversion is
|
|
-- complete, i.e. the maximum number of characters
|
|
-- maxsize is not reached by tostr before the end
|
|
-- of conversion of fromstr.
