Alphabetic is defined as Lu + Ll + Lt + Lm + Lo + Nl +
Other_Alphabetic, all of which are explained here:

I misunderstood isAlpha(), I
used to think it's to validate letters like a, b, è, é .. z
etc but
isAlpha('º') from std.uni module return true.
º happens to be in the Letter, Lowercase category so yes, it
is isAlpha().
How can I validate only
the letters of an unicode alphabet in D or should I write one?
There are so many alphabets in the world. It is likely that a
Unicode character will be a part of one.
I know I can do:
bool is_id(dchar c)
{
return c = 'a' c = 'z' || c = 'A' c = 'z' || c
= 0xc0;
}
There is a misunderstanding. There are so many Unicode
characters that are = 0xc0 but not a part of the Alphabetic
category. For example: ← (U+2190 LEFTWARDS ARROW).

If I want ASCII and latin only alphabet which range should I use?
ie, how should I rewrite is_id() function?

This seems to be it:
import std.stdio;
import std.uni;
void main()
{
alias latin = unicode.script.latin;
assert('ç' in latin);
assert('7' !in latin);
writeln(latin);
}

Sorry, I shouldn't asked for latin but an alphabet like French
instead of:
http://www.importanceoflanguages.com/Images/French/FrenchAlphabet.jpg
(including the diacritics, of course)
As you mentioned, º happend to be a letter so it still pass in:
assert('º' in latin);
so isn't different from isAlpha(). Is the UTF-8 table organized
so that I can use a range (like we do for ASCII ch = 'a' ch
= 'z' || ch = 'A' ch = 'Z') or should I put these alpha
characters myself on table and then do look up?
Re: Is º an unicode alphabetic character?
Thanks Ali, I think I get close:
bool is_id(dchar c)
{
return c = 'a' c = 'z' || c = 'A' c = 'Z' || c = 0xc0
c = 0x0d || c = 0xd8 c = 0xf6 || c = 0xf8 c = 0xff;
}
this doesn't include some math symbols. like c = 0xc0 did.
Is º an unicode alphabetic character?
what's an unicode alphabetic character? I misunderstood
isAlpha(), I used to think it's to validate letters like a, b, è,
é .. z etc but isAlpha('º') from std.uni module return true. How
can I validate only the letters of an unicode alphabet in D or
should I write one?
I know I can do:
bool is_id(dchar c)
{
return c = 'a' c = 'z' || c = 'A' c = 'z' || c = 0xc0;
}
but I'm looking for a native, if any
