ISO/IEC 646 is the name of a set of ISO standards, described as Information technology — ISO 7-bit coded character set for information interchange and developed in cooperation with ASCII at least since 1964. Since its first edition in 1967 it has specified a 7-bit character code from which several national standards are derived.

David Kent is an Australian music historian and pop culture writer. Kent produced the Kent Music Report, compiling the national music chart from May 1974 to 1996; it was known as the Australian Music Report from 1987. The music reports were a weekly listing of the National Top 100 chart positions of singles and albums. Kent's music reports were used by Australian Recording Industry Association (ARIA) as its official ARIA Charts from mid-1983 until July 1988 when ARIA developed an in-house chart.

German submarine U-646 was a Type VIIC U-boat of Nazi Germany's Kriegsmarine during World War II. The submarine was laid down on 23 December 1941 at the Blohm & Voss yard at Hamburg, launched on 3 September 1942, and commissioned on 29 October 1942 under the command of Leutnant zur See d.R. Heinrich Wulff.
Type 646 water tanker (AWT) is a type of naval auxiliary ship currently in service with the People's Liberation Army Navy (PLAN). Type 646 series ships in PLAN service are designated by a combination of two Chinese characters followed by three-digit number. The second Chinese character is Shui (水), meaning water, because these ships are classified either as oil and water tankers. The first Chinese character denotes which fleet the ship is service with, with East for East Sea Fleet, North for North Sea Fleet, and South for South Sea Fleet. However, the pennant numbers may have changed due to the change of Chinese naval ships naming convention. Two have been identified as still in active service as mid 2015:
Code page 1009, also known as CP1009 (IBM) and CP20105 (Microsoft), is the International Reference Version (IRV) of ISO 646:1983 until its redefinition in ISO/IEC 646:1991.
Code page 1013, also known as CP1013, is the code page for the United Kingdom version of ISO 646, specified in BS 4730.
Code page 1015, also known as CP1015, is IBM's code page for the Portuguese version of ISO 646.
Code page 1017, also known as CP1017, is IBM's code page for the Danish version of ISO 646 (ISO-646-DK), specified in DS 2089.
Code page 1018, also known as CP1018, is IBM's code page for the Swedish and Finnish version of ISO 646, specified in SFS 4017 and SEN 850200 Annex B, SIS 63 61 27.
Code Page 1019, also known as CP1019, is the code page for the Dutch version of ISO 646. It is roughly equivalent to ASCII, differing only in replacing the tilde with a macron.
Code page 1107, also known as CP1107, is an IBM code page number assigned to the alternate Denmark/Norway variant of DEC's National Replacement Character Set (NRCS). The 7-bit character set was introduced for DEC's computer terminal systems, starting with the VT200 series in 1983, but is also used by IBM for their DEC emulation. Similar but not identical to the series of ISO 646 character sets, the character set is a close derivation from ASCII with only six code points differing.

Code page 903 is encoded for use as the single byte component of certain simplified Chinese character encodings. It is used in China. Despite this, it follows ISO 646-JP / the Roman half of JIS X 0201, in that it replaces the ASCII backslash 0x5C with the yen/yuan sign. It also uses the same C0 replacement graphics as code page 897. When combined with the double-byte Code page 928, it forms the two code-sets of IBM code page 936.
