Detailed Description

Holds a character value and provides a number of utility functions to manipulate it and test its properties.

For example, there are functions to convert the character to uppercase and test whether or not it is a control character.

The character value is stored as a 32-bit unsigned integer. The shorthand "TChar value" is used to describe the character value wrapped by a TChar object.

TChar can be used to represent Unicode values outside plane 0 (that is, the extended Unicode range from 0x10000 to 0xFFFFF). This differentiates it from TText which can only be used for 16-bit Unicode character values.

◆ TCategory

enum TChar::TCategory

General Unicode character category.

E<XX> Category

where

<XX>

is the category name given by the Unicode database (e.g., the constant ELuCategory is used for lowercase letters, category Lu);

(ii) as numbers in certain ranges: letter categories are all <= EMaxLetterCategory;

(iii) as codes in which the upper nibble gives the category group (e.g., punctuation categories all yield TRUE for the test (category & 0xF0) ==EPunctuationGroup).

(generated from Symbian Developer Library)

(generated from Symbian Developer Library)

Member Function Documentation

◆ Compose()

static IMPORT_C TBool TChar::Compose	(	TUint &	aResult,
		const TDesC16 &	aSource
	)

static

Composes a string of Unicode characters to produce a single character result.

For example, 0061 ('a') and 030A (combining ring above) compose to give 00E5 ('a' with ring above).

A canonical decomposition is a relationship between a string of characters - usually a base character and one or more diacritics - and a composed character. The Unicode standard requires that compliant software treats composed characters identically with their canonical decompositions. The mappings used by these functions are fixed and cannot be overridden for particular locales.

Parameters

aResult	If successful, the composed character value. If unsuccessful, this value contains 0xFFFF.
aSource	String of source Unicode characters.

(generated from Symbian Developer Library)

◆ Decompose()

IMPORT_C TBool TChar::Decompose ( TPtrC16 & aResult ) const

Maps this character to its maximal canonical decomposition.

For example, 01E1 ('a' with dot above and macron) decomposes into 0061 ('a') 0307 (dot) and 0304 (macron).

Note that this function is used during collation, as performed by the Mem::CompareC() function, to convert the compared strings to their maximal canonical decompositions.

Mem::CompareC() TChar::Compose()

Parameters

IMPORT_C TBdCategory TChar::GetBdCategory ( ) const

Gets the bi-directional category of a character.

For more information on the bi-directional algorithm, see Unicode Technical Report No. 9 available at: http://www.unicode.org/unicode/reports/tr9/.

(generated from Symbian Developer Library)

◆ GetCategory()

IMPORT_C TCategory TChar::GetCategory ( ) const

Gets this character's Unicode category.

(generated from Symbian Developer Library)

◆ GetCjkWidth()

IMPORT_C TCjkWidth TChar::GetCjkWidth ( ) const

Gets the Chinese, Japanese, Korean (CJK) notional width.

Some display systems used in East Asia display characters on a grid of fixed-width character cells like the standard MSDOS display mode.

Some characters, e.g. the Japanese katakana syllabary, take up a single character cell and some characters, e.g., kanji, Chinese characters used in Japanese, take up two. These are called half-width and full-width characters. This property is fixed and cannot be overridden for particular locales.

For more information on returned widths, see Unicode Technical Report 11 on East Asian Width available at: http://www.unicode.org/unicode/reports/tr11/

(generated from Symbian Developer Library)

◆ GetCombiningClass()

IMPORT_C TInt TChar::GetCombiningClass ( ) const

The character object itself is not changed.

(generated from Symbian Developer Library)

◆ GetLowSurrogate()

static TText16 TChar::GetLowSurrogate ( TUint aChar )

inlinestatic

Retrieve the low surrogate of a supplementary character.

Parameters

aChar The 32-bit code point value of a Unicode character.

Returns: Low surrogate of aChar, if aChar is a supplementary character; zero, if aChar is not a supplementary character.

See also: TChar::GetHighSurrogate

(generated from Original Symbian implementation)

◆ GetNumericValue()

IMPORT_C TInt TChar::GetNumericValue ( ) const

Gets the integer numeric value of this character.

Numeric values need not be in the range 0..9; the Unicode character set includes various other numeric characters such as the Roman and Tamil numerals for 500, 1000, etc.

(generated from Symbian Developer Library)

◆ GetTitleCase()

IMPORT_C TUint TChar::GetTitleCase ( ) const

Gets the character value after conversion to titlecase or the character's own value, if no titlecase form exists.

The titlecase form of a character is identical to its uppercase form unless a specific titlecase form exists.

(generated from Symbian Developer Library)

◆ GetUpperCase()

IMPORT_C TUint TChar::GetUpperCase ( ) const

Gets the character value after conversion to uppercase or the character's own value, if no uppercase form exists.

The character object itself is not changed.

(generated from Symbian Developer Library)

◆ IsAlpha()

IMPORT_C TBool TChar::IsAlpha ( ) const

Tests whether the character is alphabetic.

For Unicode, the function returns TRUE for all letters, including those from syllabaries and ideographic scripts. The function returns FALSE for letter-like characters that are in fact diacritics. Specifically, the function returns TRUE for categories: ELuCategory, ELtCategory, ELlCategory, and ELoCategory; it returns FALSE for all other categories including ELmCategory.

TChar::IsAlphaDigit() TChar::TCategory

(generated from Symbian Developer Library)

◆ IsAlphaDigit()

IMPORT_C TBool TChar::IsAlphaDigit ( ) const

Tests whether the character is alphabetic or a decimal digit.

It is identical to (IsAlpha()||IsDigit()).

TChar::IsAlpha() TChar::IsDigit()

(generated from Symbian Developer Library)

◆ IsAssigned()

IMPORT_C TBool TChar::IsAssigned ( ) const

Tests whether this character has an assigned meaning in the Unicode encoding.

All characters outside the range 0x0000 - 0xFFFF are unassigned and there are also many unassigned characters within the Unicode range.

Locales can change the assigned/unassigned status of characters. This means that the precise behaviour of this function is locale-dependent.

(generated from Symbian Developer Library)

◆ IsControl()

IMPORT_C TBool TChar::IsControl ( ) const

Tests whether the character is a control character.

For Unicode, the function returns TRUE for all characters in the categories: ECcCategory, ECfCategory, ECsCategory, ECoCategory and ECnCategoryCc.

TChar::TCategory

(generated from Symbian Developer Library)

◆ IsDigit()

IMPORT_C TBool TChar::IsDigit ( ) const

Tests whether the character is a standard decimal digit.

For Unicode, this function returns TRUE only for the digits '0'...'9' (U+0030...U+0039), not for other digits in scripts like Arabic, Tamil, etc.

TChar::GetCategory() TChar::GetNumericValue

(generated from Symbian Developer Library)

◆ IsGraph()

IMPORT_C TBool TChar::IsGraph ( ) const

Tests whether the character is a graphic character.

For Unicode, graphic characters include printable characters but not the space character. Specifically, graphic characters are any character except those in categories: EZsCategory,EZlCategory,EZpCategory, ECcCategory,ECfCategory, ECsCategory, ECoCategory, and ,ECnCategory.

Note that for ISO Latin-1, all alphanumeric and punctuation characters are graphic.

TChar::TCategory

(generated from Symbian Developer Library)

◆ IsHexDigit()

IMPORT_C TBool TChar::IsHexDigit ( ) const

Tests whether the character is a hexadecimal digit (0-9, a-f, A-F).

(generated from Symbian Developer Library)

(generated from Original Symbian implementation)

◆ IsMirrored()

IMPORT_C TBool TChar::IsMirrored ( ) const

Tests whether this character has the mirrored property.

Mirrored characters, like ( ) [ ] < >, change direction according to the directionality of the surrounding characters. For example, an opening parenthesis 'faces right' in Hebrew or Arabic, and to say that 2 < 3 you would have to say that 3 > 2, where the '>' is, in this example, a less-than sign to be read right-to-left.

(generated from Symbian Developer Library)

◆ IsPrint()

IMPORT_C TBool TChar::IsPrint ( ) const

Tests whether the character is a printable character.

For Unicode, printable characters are any character except those in categories: ECcCategory, ECfCategory, ECsCategory, ECoCategory and ECnCategory.

TChar::TCategory

(generated from Symbian Developer Library)

◆ IsPunctuation()
