Lotus International Character Set
From HandWiki
The Lotus International Character Set (LICS) is a proprietary single-byte character encoding introduced in 1985 by Lotus Development Corporation. It is based on the 1983 DEC Multinational Character Set (MCS) for VT220 terminals. As such, LICS is also similar to two other descendants of MCS, the ECMA-94 character set of 1985[1] and the ISO 8859-1 (Latin-1) character set of 1987. LICS was first introduced as the character set of Lotus 1-2-3 Release 2 for DOS in 1985.[2][3][4][5] It is also utilized by 2.01,[3][4][5] 2.2,[6][7][5] 2.3 and 2.4[8][9][10][11] as well as by Symphony. It was also utilized in a number of third-party spreadsheet products emulating the file format. LICS was superseded by the Lotus Multi-Byte Character Set (LMBCS) introduced by Lotus 1-2-3 Release 3 in 1989.[11]
Character set
Codepoints 20hex (32) to 7Fhex (127) are identical to ASCII (as well as to LMBCS).[11] For some characters the table also lists dedicated Lotus 1-2-3 compose key sequences to ease character input beyond the Alt Numpad input method.

"Since 1982 the urgency of the need for an 8-bit single-byte coded character set was recognized in ECMA as well as in ANSI/X3L2 and numerous working papers were exchanged between the two groups. In February 1984 ECMA TC1 submitted to ISO/TC97/SC2 a proposal for such a coded character set. At its meeting of April 1984 SC decided to submit to TC97 a proposal for a new item of work for this topic. Technical discussions during and after this meeting led TC1 to adopt the coding scheme proposed by X3L2. Part 1 of Draft International Standard DTS 8859 is based on this joint ANSI/ECMA proposal....Adopted as an ECMA Standard by the General Assembly of Dec. 13–14, 1984."

With Release 2, Lotus has assigned different meanings to these characters, the Lotus International Character Set, LICS. Any these extended characters must be erased or replaced with regular keyboard characters before the character can appear acceptable on an Release 2 screen. Release 2.01 offers an install option to use extended characters rather than LICS characters."
