Patch 7.4.505
|
|
|
22c937 |
Problem: On MS-Windows when 'encoding' is a double-byte encoding a file
|
|
|
22c937 |
name longer than MAX_PATH bytes but shorter than that in
|
|
|
22c937 |
characters causes problems.
|
|
|
22c937 |
Solution: Fail on file names longer than MAX_PATH bytes. (Ken Takata)
