2-78 Sun StorEdge 5310 NAS Troubleshooting Guide • December 2004
Log message “mbtowc[0xXX]: invalid first byte”, or “: invalid
sequence”.
This message is generated when StorEdge receives a filename or network name with
a character that is unreadable. ASCII (plain text) characters are expressed with a byte
value of 0x7F or below. Values above this range are expected to be Unicode encoded,
per the UTF-8 specification. The encoding requires multiple bytes per character. In
order for the character to be valid, the first byte must be in the range 0xC0 through
0xFD. All other bytes in the sequence must be in the range 0x80 to 0xBF. When the
character is out of these ranges, the invalid first byte or invalid sequence message is
generated.
The most likely source of this is a client sending non-ASCII names that are not
Unicode encoded. It can also be an indication that NFS clients are not properly set
up for Unicode.
