 .Sh NAME
 .Nm big5
 .Nd
 .Dq "Big Five"
 encoding for Traditional Chinese text
 .Sh SYNOPSIS
 .Nm ENCODING
 .Qq BIG5
 .Sh DESCRIPTION
 .Dq Big Five
-is the de facto standard for encoding Traditional Chinese text.
+is a standard for encoding Traditional Chinese text.
 Each character is represented by either one or two bytes.
 Characters from the
 .Tn ASCII
 character set are represented as single bytes in the range 0x00 - 0x7F.
 Traditional Chinese characters are represented by two bytes:
 the first in the range 0xA1 - 0xFE, the second in the range
 0x40 - 0xFE.
 .Sh SEE ALSO
 .Xr euc 5 ,
 .Xr gb18030 5 ,
 .Xr utf8 5
+.Sh BUGS
+The range of the second byte overlaps some ASCII characters, including
+0x5C (`\\') and 0x7C (`|') which may cause problems in program execution or
+display.
+Big5 is considered a legacy standard and only preserved for backward
+compatibility reason.
+New documents and systems are suggested using UTF-8 directly.
