PRB: Problem w/Traditional Chinese Windows 3.1 DBCS File Names

• Microsoft Windows version 3.1 Traditional Chinese version
• Microsoft Windows Software Development Kit (SDK) 3.1

SYMPTOMS

Sometimes traditional Chinese Windows version 3.1 will say a Chinese filename is invalid even though there is no obvious reason for it. Or sometimes the Chinese file names are changed slightly when saved.

CAUSE

The reason is that CWIN31 used the original MS-DOS file system as its file system because Microsoft never released a Chinese MS-DOS in Taiwan. Therefore all of the localized Chinese DOS systems are third-party products. Microsoft only delivered device drivers (such as printer/display drivers) to interpret the Chinese character. As a result, the file name system is still a SBCS (single byte character set) system. The Lead byte of an MS-DOS file name has never been checked using DBCSLeadByte filtering. CWIN31 will display or treat a DBCS (double byte character set) filename as an erroneous file name when you try to dump or search the DBCS file.

STATUS

This behavior is by design.
