Hello world,

J3 has passed https://j3-fortran.org/doc/year/24/24-116.txt , a
proposal for unsigned numbers in Fortran, in their February/March
meeting.

Gfortran 15, to be released in the beginning of 2025, will contain
an experimental implementation of that proposal. The current
development version already has that documentation, so if you
are so inclined, you can download and compile it for yourself to
try it out already.

This feature can be accessed by using the -funsigned flag.
Some short documentation can be found at

https://gcc.gnu.org/onlinedocs/gfortran/Unsigned-integers.html

Test cases (also doubling as use examples) can be found at https://gcc.gnu.org/git/?p=gcc.git;a=tree;f=gcc/testsuite/gfortran.dg
(any file that has "unsigned" in its name).

Bug reports and comments are welcome.

Enjoy!

Best regards

Thomas

Yay? :) I'm so used to using larger signed integers and various tricks
that I'll probably never use it, but at least I have the option now.

Do you mean “unsigned integers”?

https://gcc.gnu.org/onlinedocs/gfortran/Unsigned-integers.html

Thought so.

Any plans to support UTF16 or UTF8 in gfortran ?

Thanks,
Lynn

gfortran has supported UTF-8 for long time now. Here's
an example from the manual.


program character_kind
use iso_fortran_env
implicit none
integer, parameter :: ascii = selected_char_kind ("ascii")
integer, parameter :: ucs4 = selected_char_kind ('ISO_10646')

character(kind=ascii, len=26) :: alphabet
character(kind=ucs4, len=30) :: hello_world

alphabet = ascii_"abcdefghijklmnopqrstuvwxyz"
hello_world = ucs4_'Hello World and Ni Hao -- ' &
// char (int (z'4F60'), ucs4) &
// char (int (z'597D'), ucs4)

write (*,*) alphabet

open (output_unit, encoding='UTF-8')
write (*,*) trim (hello_world)
end program character_kind

No UTF-16, please!

That was just a horrible backward-compatibility hack for the sake of those platforms (*cough* Java, Windows NT *cough*) that embraced Unicode as
their native encoding just a little too soon.

Aren't all of the Unix and Linux boxen either UTF-16 or UTF-32 ?

No!

A friend of mine was working on a PLC in Japan a couple of decades ago.
It was very custom Unix and UTF-32. He was shocked. He had several
problems porting their software to the PLC.

Most certainly not:

$ echo $LANG
de_DE.UTF-8

Haven't seen anything but UTF-8 in a long time.

Come over here to Windows. UTF-16 is the name of the game. It is a
total pain.

Microsoft is rumored to be working on a UTF-8 API for Win32 / Win64. I
will believe it when I see it.

Microsoft (and Sun, with Java) adopted Unicode at precisely the wrong
time, back when everybody believed the Unicode folks who said that it
would remain a fixed-length 16-bit code.

Linux simply ignored the issue. Filespecs passed to the kernel are split
at ASCII “/” characters and terminated by NUL. And those are the only byte values with special interpretations; file/directory names are free to
contain anything else. As a result, it works seamlessly with UTF-8.

It was probably an economic decision on Microsoft's part with having to
ship different versions of DOS and Windows with English, French,
Russian, Chinese, Japanese, etc, etc, etc back in the 1980s. UTF-8 came
out in the middle 1990s ??? I suspect that they wanted to ship just one version of Windows, Office, etc and have it automatically acclimate to
the user's desired main language.

Several countries mandated that large software shops ship their
countries native language in their software. France and Quebec were the guiltiest of this. I actually have a French version of Microsoft Office
95 over in my cabinet.
