unicode (UCS-2 encoded)

[wael]

hello all,
i want convert w_char to UCS2 encoded (0041) this is a char encoded UCS2
please look at this
http://www.unicode.org/charts/
http://www.unicode.org/

every language has a chart
bye example
char 'A' = 0041--> (UCS encoded)

char 'any other language' = 0628 (this is in differ language)
i hope you uderstand what i mean

thank you for take time read this
best regards
wael ahmed

Do you mean that you want to convert locale specific strings like ASCII,
utf8, big5, etc into unicode UCS2 two byte entities, and then store them in
a wchar_t?

When porting a web browser, we had a type tChar16 to put unicode into; it's
worthwhile using typedefs anyway, even though C++ has wchar_t. We wrote our
own language conversion libraries, it depends what you want to do. It's
probably not so much of a C++ question. Look up internationaliz ation on the
web, in relation to C++

i have wchar_t charcter
suppose it is (16 bit) and like this

wchar_t ch = L'A';
//char A encoded UCS-2 is 0041
how do i get ch in 2 bytes UCS encoded ??
some data stored in data base UCS-2
0041 0065 etc ... 0628 0627 ....
thank you for take time read this

Like this?

wchar_t ch = L'A';
char bytes[2];
bytes[0] = ch/256; // byte[0] == 0x00
bytes[1] = ch%256; // byte[1] == 0x41

Still not completely clear what you are trying to do.

I am afraid I don't understand the question either. Perhaps you can tell us
what data your reading, and if it's in Unicode or ASCII and what you want to
do with it. Instead of talking about wchar_t's and UCS-2 straight away.

wchar_t ch = L'A';
char bytes[2];
bytes[0] = ch/256; // byte[0] == 0x00
bytes[1] = ch%256; // byte[1] == 0x41

thank you for help ,
let me be more clear:-
1- i receive text from ascii socket like this ( i will assume it is on
{0041 , 0628 , 0627 , 0042}
each 4 chars is UCS-2 encoded hex as defined in
http://www.unicode.org/charts/
00 prifx for english 41 char as defined in chart
http://www.unicode.org/charts/PDF/U0000.pdf
06 prifx for arabic 28 is char as defined in chart
http://www.unicode.org/charts/PDF/U0600.pdf
also i receive data for other languages like greek

i want convert incoming string to wchar_t and from wchar_t to send it
by socket

OK, try again, perhaps like this?

ascii_data is your string of unicode numbers seperated by commas and with a
leading { and trailing }. I.e. what you read from the socket. At the end
unicode_data is a wide string of Unicode characters, you can write that to
your other socket.

#include <algorithm>
#include <istream>
#include <sstream>
#include <string>

int main()
{
std::string ascii_data = "{0041 , 0628 , 0627 , 0042}";
// remove leading and trailing {}
ascii_data.eras e(ascii_data.be gin());
ascii_data.eras e(ascii_data.en d() - 1);
// replace commas with spaces
std::replace(as cii_data.begin( ), ascii_data.end( ), ',', ' ');
// use string as stream
std::istringstr eam str(ascii_data) ;
// read hex numbers from stream
std::wstring unicode_data;
unsigned char_value;
while (str >> std::hex >> char_value)
{
unicode_data.pu sh_back(static_ cast<wchar_t>(c har_value));
}
}

sorry ,
//bytes order
this was by mistake
//i am sorry if i can not let you understand may be for my bad language
i try encode wchar according 'The Unicode Standard and ISO/IEC 10646'
this is the format which i need
please look at:
Figure 1-1. Wide ASCII
http://www.unicode.org/book/uc20ch1.html
the picture display how chars look like in binary format
You will find 'A' is = '0000 0000 0100 0001' = (in hex) '0 0 4 1'
Other char down (arabic char) = '0000 0110 0011 0011' = in hex '0 6 3 3'
the problem is if i try get the binary string of this arabic char
it is '0000 0000 1101 0011' which != '0000 0110 0011 0011'
for that i must convert '0000 0000 1101 0011' to ISO/IEC 10646'

sorry for distrub you john
and thank you for try help me

thanks

Wael, at last I think I understand you!

You have characters encoded in one character set and you want to convert
them to Unicode. Do you know which character set you have currently? I think
there are two commonly used character sets for Arabic, one is IS0-8859-6,
the other is CP1256 Do you know which you have?

Whatever you have it should just a be a simple matter of setting up a table
to convert between them.

Here is a table that converts CP1256 to Unicode

http://www.unicode.org/Public/MAPPIN...OWS/CP1256.TXT

and here's a table that converts ISO-8859-6 to Unicode

http://www.unicode.org/Public/MAPPIN...859/8859-6.TXT

Hope this helps.
john

You have characters which are encoding using IS0-8859-6 (Arabic)
