Re: [Dev-C++] Using Unicode in Dev-C++

From: Per W. <pw...@ia...> - 2007-04-26 13:00:26

There are windows API calls to convert between Unicode and MBCS (MultiByte
Character Set).

You can _never_ convert unicode to ANSI (other than for the characters
that fit in the ANSI character set).

You want to use a Unicode-compatible editor, i.e. an editor that checks if
there are a magic marker in the beginning of the file to inform that the
file is not ASCII (or ANSI or whatever single-byte format) but either UTF8
or UTF16.

Additional to the answer of Per Westermark you could take a look to this 
Wikipedia article for a better / deeper understanding of the coherences 
of UTF along with operating systems, editors, e-mails, web, fonts, 
storage, converters and ... a lot more:

http://en.wikipedia.org/wiki/Unicode

[Dev-C++] How to find out code page in DOS Command Prompt

From: Jan M. <jan...@vo...> - 2007-05-02 09:08:18

Hello,

I would like to ask if there is a way to find out which code page
iscurrently set for Command Prompt in Windows (I use XP Prof).

I have tried to use somthing like

...
cp = system("chcp");
printf ("%d", cp);


But there is always 0 in return value cp.
The return values should be an implementation defined. So are they
implemtented in Windows? Did I a mistake?

Thank you.

First of all system("") basically starts a new console for running the
command. I'm not sure if you can guarantee that the new environment
inherrits every characteristic from your application.

Second - the cp variable is not the answer for the chcp command. It is the
return value. In this case, a value of 0 means that the command executed
ok. It corresponds to the value you send to the function exit(), or the
return value when you leave the main() function.

When you use system() to run a command, that command will emit it's
answers to stdout - i.e. it will print the information. Not return it as
a value for system() to return.

Go to the Microsoft MSDN web site. They have a complete reference of the
Win32 API. There, you can find a huge amount of functions that you can
call directly from your code. Real functions, producing real answers.
There, you have a lot of information about current locale, code pages etc.

Hello,

thank you for the hint and the explanation.=20
