On second thought, since we have a major change upcoming,
perhaps I will commit this tomorrow to allow for more testing.
(No one uses this stuff currently anyways.)
On Mon, Aug 12, 2002 at 02:18:05AM +0800, Chia-liang Kao scribbled:
| attached is a patch implmenting SWIDTH[0-3] in mklocale and wcwidth in
| libc. it is obtained from netbsd/citrus code.
|
| the share_mklocale files shall be updated with the SWIDTH info as the
| ASCII one in the patch.
|
| should there be a default value for SWIDTH in each locale file? should
| we maintain the binary file format compatibility? I think ache is
| making the loading of locale files graceful.
|
| Cheers,
| CLK
