String Constructor

[Kevin]

Hello,

So there seems to be something a little strange going on with the String constructor

Code: Select all

CEGUI::String(const char* chars, CEGUI::String::size_type chars_len);

I've tried a few small tests, and it seems to work as expected. However, when I pass it a 32 character string (of unsigned chars) full of character 10001000, I get back the 16 character string:

Code: Select all

11000011 10001000 11000010 10001000 11000011 10001000 11000010 10001000 11000011 10001000
11000010 10001000 11000011 10001000 11000010 10001000

A few similar tests suggest that the problem is something to do with the original string containing negative value characters, but I'm not sure if that's the problem exactly.

Hi,

Thanks for the report. I'll have a look

Hello,

As a follow-up, it seems there is a similar problem (or perhaps the same problem?) with the c_str() function.

Code: Select all

CEGUI::String str(32, ' ');
for (CEGUI::String::size_type i = 0; i < 32; i++)
{
  str[i] = 0xff;
}
const char* ch = str.c_str();

After executing, str has length 32, but ch has 64 characters before the null - 32 of each 0xc3 and 0xbf (alternating).

Then executing a similar loop:

Code: Select all

for (CEGUI::String::size_type i = 0; i < 32; i++)
{
  char ch2 = str[i];
}

works as expected - after each iteration ch2 is 0xff.
