SYMPTOMS
The gatherer logs that are generated by the Microsoft SharePoint Portal Server indexing process do not show double-byte character set (DBCS) strings correctly.



CAUSE
This issue occurs because the module that treats the gatherer logs does not handle double-byte character set strings correctly.



MORE INFORMATION
Gatherer log files are created during every index update. The log files are stored in the following folder:

Data\FTData\SharePointPortalServer\GatherLogs\

This folder is typically located in ProgramFiles\SharePointPortalServer on the drive where you installed the SharePoint Portal Server program files. For additional information about how to use the Gthrlog.vbs utility to view gatherer logs, click the following article number to view the article in the Microsoft Knowledge Base:

Double-byte character set is a character-encoding mechanism that is used to handle ideographic characters in Asian languages. Single-byte character sets (SBCSs) only use one byte to represent each character, so they can only represent up to 256 characters. But DBCSs uses two bytes (or 16-bit notation), so a DBCS can represent up to 65,536 (2^16) characters.

DBCS code pages contain both single and double-byte characters. The DBCS single-byte characters comply with the 8-bit national standards for each country and correspond closely to the ASCII character set.

In a double-byte character set, certain ranges of code-points are designated as leading bytes. A leading byte, together with the following byte, represents a single character. This second byte is named the trailing byte or trail byte. Each DBCS has a different set of lead-byte ranges and trail-byte ranges. Unlike leading bytes, trail-bytes in some DBCSs can overlap with the 7-bit ASCII character set. For example, the Shift JIS (Japan Industry Standard) character set has a trail-byte range of 0x40H-0xFEH. That means a byte that holds the value of 0x7DH can represent the second half of a Kanji character, not necessarily a close brace character (}) as it would with the 7-bit ASCII set.
