Subprograms & Entries

UTF8_Validate 

procedure UTF8_Validate 
(Str: UTF8_String;
Valid: out Boolean;
Invalid_Pos: out Natural);
Validate a UTF8 string. Set Valid to True if valid, set Invalid_Pos to first invalid byte.

Is_Space 

function Is_Space 
(Char: Gunichar) return Boolean;
True if Char is a space character

Is_Alnum 

function Is_Alnum 
(Char: Gunichar) return Boolean;
True if Char is an alphabetical or numerical character

Is_Alpha 

function Is_Alpha 
(Char: Gunichar) return Boolean;
True if Char is an alphabetical character

Is_Digit 

function Is_Digit 
(Char: Gunichar) return Boolean;
True if Char is a digit

Is_Lower 

function Is_Lower 
(Char: Gunichar) return Boolean;
True if Char is a lower-case character

Is_Upper 

function Is_Upper 
(Char: Gunichar) return Boolean;
True if Char is an upper-case character

Is_Punct 

function Is_Punct 
(Char: Gunichar) return Boolean;
True if Char is a punctuation character

Unichar_Type 

function Unichar_Type 
(Char: Gunichar) return G_Unicode_Type;
Return the unicode character type of a given character

To_Lower 

function To_Lower 
(Char: Gunichar) return Gunichar;
Convert Char to lower cases

To_Upper 

function To_Upper 
(Char: Gunichar) return Gunichar;
Convert Char to upper cases

UTF8_Strdown 

function UTF8_Strdown 
(Str: ICS.chars_ptr;
Len: Integer) return ICS.chars_ptr;

UTF8_Strdown 

function UTF8_Strdown 
(Str: UTF8_String) return UTF8_String;
Convert Str to lower cases

UTF8_Strup 

function UTF8_Strup 
(Str: ICS.chars_ptr;
Len: Integer) return ICS.chars_ptr;

UTF8_Strup 

function UTF8_Strup 
(Str: UTF8_String) return UTF8_String;
Convert Str to upper cases

UTF8_Strlen 

function UTF8_Strlen 
(Str: ICS.chars_ptr;
Max: Integer := -1) return Glong;

UTF8_Strlen 

function UTF8_Strlen 
(Str: UTF8_String) return Glong;
Return the number of characters in Str

UTF8_Find_Next_Char 

function UTF8_Find_Next_Char 
(Str: ICS.chars_ptr;
Str_End: ICS.chars_ptr := ICS.Null_Ptr) return ICS.chars_ptr;

UTF8_Find_Next_Char 

function UTF8_Find_Next_Char 
(Str: UTF8_String;
Index: Natural) return Natural;

UTF8_Next_Char 

function UTF8_Next_Char 
(Str: UTF8_String;
Index: Natural) return Natural;

UTF8_Find_Prev_Char 

function UTF8_Find_Prev_Char 
(Str_Start: ICS.chars_ptr;
Str: ICS.chars_ptr) return ICS.chars_ptr;

UTF8_Find_Prev_Char 

function UTF8_Find_Prev_Char 
(Str: UTF8_String;
Index: Natural) return Natural;
Find the start of the previous UTF8 character after the Index-th byte. Index doesn't need to be on the start of a character. Index is set to a value smaller than Str'First if there is no previous character.

Unichar_To_UTF8 

function Unichar_To_UTF8 
(C: Gunichar;
Buffer: ICS.chars_ptr := ICS.Null_Ptr) return Natural;

Unichar_To_UTF8 

procedure Unichar_To_UTF8 
(C: Gunichar;
Buffer: out UTF8_String;
Last: out Natural);
Encode C into Buffer. Buffer must have at least 6 bytes free. Return the index of the last byte written in Buffer.

UTF8_Get_Char 

function UTF8_Get_Char 
(Str: UTF8_String) return Gunichar;
Converts a sequence of bytes encoded as UTF8 to a unicode character. If Str doesn't point to a valid UTF8 encoded character, the result is undefined.

UTF8_Get_Char_Validated 

function UTF8_Get_Char_Validated 
(Str: UTF8_String) return Gunichar;
Same as above. However, if the sequence if an incomplete start of a possibly valid character, it returns -2. If the sequence is invalid, returns -1.
