.Sh DESCRIPTION
|
|
.Dq Big Five
|
|
is a standard for encoding Traditional Chinese text.
|
|
Each character is represented by either one or two bytes.
|
|
Characters from the 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.
|
|

.Xr euc 5 ,
|
|
.Xr gb18030 5 ,
|
|
.Xr utf8 5
|
|
.Sh BUGS
|
|
The range of the second byte overlaps some ASCII characters, including
|
|
0x5C
|
|
.Pq Ql \e
|
|
and 0x7C
|
|
.Pq Ql |
|
|
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.
