--- Comment #9 from Jussi Judin jjudin+wine@iki.fi 2011-05-01 13:55:58 CDT --- Created an attachment (id=34419) --> (http://bugs.winehq.org/attachment.cgi?id=34419) Program to create chosen length file names with single 3-byte UTF-8 character
Here's a small program to test creation of file names with multibyte characters in them. File names that have UTF-8 length over 255 won't work in Wine on NTFS file system even though they will work in Windows (tested in Windows 2000), as long as UTF-16 length is less than 256. File names that have their length in shorter than 256 UTF-8 bytes will be created successfully.
Here's the program output on Windows 2000:
C:>unicode-file-create 255 UTF-8 length: 765 UTF-16 length: 255 Great success Closed: 1
C:>unicode-file-create 256 UTF-8 length: 768 UTF-16 length: 256 Error: 123
C:>unicode-file-create 257 UTF-8 length: 771 UTF-16 length: 257 Error: 3
And with Wine 1.3.18:
jussi@jussiblet:/tmp/ntfsfs-mnt$ wine unicode-file-create.exe 85 UTF-8 length: 255 UTF-16 length: 85 Great success Closed: 1
jussi@jussiblet:/tmp/ntfsfs-mnt$ wine unicode-file-create.exe 86 UTF-8 length: 258 UTF-16 length: 86 Error: 2
jussi@jussiblet:/tmp/ntfsfs-mnt$ wine unicode-file-create.exe 87 UTF-8 length: 261 UTF-16 length: 87 Error: 2
And I did encounter this problem in real-world application usage that led me to investigate that what did that file creation failure message in logs with error code 2 meant. So this didn't come up just in some theoretical Wine's file creation limit testing.
