[CW] Impressive Morse Sending

[D.J.J. Ring, Jr.]

Chinese being a pictograph based language communicates in Morse code by
using a numerical lookup table.

A codebook is provided for encoding and decoding the Chinese telegraph
code. It shows one-to-one correspondence between Chinese characters and
four-digit numbers from 0000 to 9999.

The People's Republic of China’s Standard Telegraph Codebook (Ministry of
Post and Telecommunications 2002) provides codes for approximately 7,000
Chinese characters.

CCC was used in the old days for transmitting Chinese text over Electronic
Telegraphic/Cable. With the advance in computer communications, there is
little need to use CCC/CTC for communicating in Chinese. But for
non-Chinese speaking countries, there is still a need to identify a Chinese
person's name without using Chinese Characters. CCC has been used by those
countries in visa and immigration applications. We provided this lookup
utility here for your convenience. The data for the lookup are extracted
from the Unihan Database of www.unicode.org, with non-Hanzi telegraph codes
supplied by Jaemin Chung. For more information on the history of CTC,
please read Jim Reeds' CTC page.

Telegraph was introduced to China in 1871 by the Great Northern Telegraph
Company, with a code book of 5454 Chinese characters. In the end of 1880s,
the Qing Dynasty government published and used a new code book with about
6800 characters arranged in Kangxi Dictionary's radical order. A complete
code book was compiled in 1911 by the ROC government with about 9800
characters (original code) and used until 1949 with minor changes. After
1949, Taiwan generally kept the original code assignments (0000-9763,
9801-9824, 9901-9931). It only added some characters such as additional
Chinese characters at 9764-9798, punctuation marks at 9851-9862, and Latin
letters at 9871-9896. On the other hand, since the establishment of the
PRC, Mainland China made a lot of changes in 1952, 1958 and 1983 to the
original code assignments due to the Chinese character simplification and
the need for new characters and symbols. The result is that Taiwan and
Mainland have their own respective versions of code with both similarities
and differences.
