SYMPTOMS
A Windows NT client or server that receives EBCDIC characters from an IBM- compatible computer does not convert properly from EBCDIC character codes to ANSI character codes. For example, a received string may be garbled.
CAUSE
This problem occurs because the default conversion table does not map some characters as needed. Also, according to DCE (Distributed Computing Environment) specifications, the RPC (remote procedure calls) NDR (network data representation) does not provide information about code pages to the RPC layer. In other words, incoming data does not supply to the RPC receiver (client or server) any information about the code set or code page of the sender (client or server). This means that 1) the IBM-compatible computer can have a symmetrical problem when converting from a specific ANSI code page that is valid for a particular locale; and 2) the RPC layer cannot convert properly based on the information from the received data.
RESOLUTION
The default conversion table has been changed to default to mapping from 1047 IBM EBCDIC code set to 1252 ANSI code page. This hotfix works properly for IBM and Microsoft systems that use the indicated default code set/code page.
