D.gnu - Iteration on UTF/UNICODE characters

Hey all,

I am building a font glyph atlas for 2D and 3D rendering using 
the following code:

dchar c = '\u0000';
while (c <= '\U0000FFFF') {
   if(isValidDchar(c)){

   }
}

This compiles, and works as expected using DMD, and LDC2.

However when I try and build the code using GDC, it gives me the 
following error:

src/font.d:95:15: error: invalid UTF character \U0000FFFF

Any thoughts on why this is happening in GDC, since it works in 
DMD and LDC2 ?
And any idea how to fix this ?

Kind regards,
Danny

What GDC version?

void main()
{
     dchar c = '\u0000';
     while (c <= '\U0000FFFF') {
     }
}

compiles here with gdc (GDC 2.081.2) 8.2.0

I am using the GDC2 compiler from the Ubuntu Repository (I guess 
this is a really old version of gdc)

gdc --version

   gdc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609

Guess I will have to manually install the latest version, I was 
hoping to be able to use the version in the Ubuntu packages, to 
have the requirements for the program be:

apt install gdc

I will try to use the newest version, see if it can compile the 
code

Thanks,
Danny

gcc-5 is nearly 4 years old!

You'd probably have better luck switching to the current LTS release
of Ubuntu, which installs gcc-7 by default, which is a reasonable
version to start from.
