Wide characters support

Wide characters support

[Ludovic Courtès]

Hi,

Are there any concrete plans for wide-character support in Guile?  (I
only found mentions of it in the list archive that dated back to several
years)

Thanks,
Ludovic.

Well, my current plans are to get us Unicode support by having three
kinds of strings, with three widths (8, 16 and 32 bits, of course).
But they are not very concrete.  I am not thinking about using
wchar_t.

Because of its potential greediness in terms of memory consumption?

Thanks,
Ludovic.

Yes, but mostly because I think the type is not really an important
ingredient when using Unicode exclusively, since we know concretely
what we want and don't need to rely on wchar_t as a portability aid.
(There will of course be functions to convert Guile strings into
wchar_t arrays.)

One of the goals of moving SRFI 13 and 14 into the core was to
discourage people from relying on the internal representation of
strings.  This means that this internal representation can be changed
more easily, for example, to a multibyte encoding or to use splay
trees, etc.

Right.  And is it something you would like to have for 1.8 or is it a
longer-term goal?

Thanks,
Ludovic.

Unicode should come immediately after 1.8 is released.
