Hi,
Vim cannot open a file if the path is exactly 259 characters (MAX_PATH - 1)
and 'enc' is set to utf-8 on Windows.
Following patch fixes the problem:
--- a/src/os_mswin.c
+++ b/src/os_mswin.c
@@ -411,7 +411,7 @@ mch_FullName(
* - convert the result from UCS2 to 'encoding'.
*/
wname = enc_to_utf16(fname, NULL);
- if (wname != NULL && _wfullpath(wbuf, wname, MAX_PATH - 1) != NULL)
+ if (wname != NULL && _wfullpath(wbuf, wname, MAX_PATH) != NULL)
{
cname = utf16_to_enc((short_u *)wbuf, NULL);
if (cname != NULL)
MAX_PATH is defined as 260 and it includes the last NUL.
The third parameter of _wfullpath() is length of the buffer including NUL, so
"- 1" is not needed. (http://msdn.microsoft.com/en-us/library/506720ff.aspx)
Note: This problem is different from
