ConvertFullHiragnaToFullKatakana(const TDesC16 &, TDes16 &)

IMPORT_C TInt ConvertFullHiragnaToFullKatakana ( const TDesC16 & aUnicodeSource,
TDes16 & aUnicodeTarget
) [static]

Converts Full-width Hiragana and Special Character text found in aUnicodeSource to their Full-width counterparts and places the resulting text into aUnicodeTarget.

Parameters

const TDesC16 & aUnicodeSource Descriptor that contains the text to be converted.
TDes16 & aUnicodeTarget The target descriptor for the converted text.

ConvertFullToHalfWidth(const TDesC16 &, TDes16 &)

IMPORT_C TInt ConvertFullToHalfWidth ( const TDesC16 & aUnicodeSource,
TDes16 & aUnicodeTarget
) [static]

Converts all Full-width conformant text found in aUnicodeSource to their Half-width counterparts and places the resulting text into aUnicodeTarget. Only those characters with existing Half-width variants are converted. There will be a 2-for-1 conversion for each Full-width Voiced and Semi-voiced Katakana character.

Parameters

const TDesC16 & aUnicodeSource Descriptor that contains the text to be converted.
TDes16 & aUnicodeTarget The target descriptor for the converted text.

ConvertFullToHalfWidthKatakana(const TDesC16 &, TDes16 &)

IMPORT_C TInt ConvertFullToHalfWidthKatakana ( const TDesC16 & aUnicodeSource,
TDes16 & aUnicodeTarget
) [static]

Converts Full-width Katakana and Special Character text found in aUnicodeSource to their Half-width counterparts and places the resulting text into aUnicodeTarget. There will be a 2-for-1 conversion for each Full-width Voiced and Semi-voiced Katakana character.

Parameters

const TDesC16 & aUnicodeSource Descriptor that contains the text to be converted.
TDes16 & aUnicodeTarget The target descriptor for the converted text.

ConvertHalfToFullWidth(const TDesC16 &, TDes16 &)

IMPORT_C TInt ConvertHalfToFullWidth ( const TDesC16 & aUnicodeSource,
TDes16 & aUnicodeTarget
) [static]

Converts all Half-width conformant text (including ASCII, Special Characters and Katakana) found in aUnicodeSource to their Full-width counterparts and places the resulting text into aUnicodeTarget.

Parameters

const TDesC16 & aUnicodeSource Descriptor that contains the text to be converted.
TDes16 & aUnicodeTarget The target descriptor for the converted text.

ConvertHalfToFullWidthKatakana(const TDesC16 &, TDes16 &)

IMPORT_C TInt ConvertHalfToFullWidthKatakana ( const TDesC16 & aUnicodeSource,
TDes16 & aUnicodeTarget
) [static]

Converts Half-width Katakana and Special Character text found in aUnicodeSource to their Full-width counterparts and places the resulting text into aUnicodeTarget.

Parameters

const TDesC16 & aUnicodeSource Descriptor that contains the text to be converted.
TDes16 & aUnicodeTarget The target descriptor for the converted text.

IsFullWidth(const TText)

IMPORT_C TBool IsFullWidth ( const TText aUnicodeChar ) [static]

Returns ETrue if aUnicodeChar is Full-width. Essentially, all text that is not Half-width.

Parameters

const TText aUnicodeChar The unicode character to test.

IsHalfWidth(const TText)

IMPORT_C TBool IsHalfWidth ( const TText aUnicodeChar ) [static]

Returns ETrue if aUnicodeChar is Half-width according to the UNICODE definition of the term.

Parameters

const TText aUnicodeChar The unicode character to test.

IsHiragana(const TText)

IMPORT_C TBool IsHiragana ( const TText aUnicodeChar ) [static]

Returns ETrue if aUnicodeChar is Hiragana. There are no Half-width Hiragana variants.

Parameters

const TText aUnicodeChar The unicode character to test.

IsKanji(const TText)

IMPORT_C TBool IsKanji ( const TText aUnicodeChar ) [static]

Returns ETrue if aUnicodeChar is Kanji, or CJK ideographic All characters in the CJK ideographic range are Full-width.

Parameters

const TText aUnicodeChar The unicode character to test.

IsKatakana(const TText)

IMPORT_C TBool IsKatakana ( const TText aUnicodeChar ) [static]

Returns ETrue if aUnicodeChar is Katakana. This includes both Full and Half-width Katakana.

Parameters

const TText aUnicodeChar The unicode character to test.
