Lotus Multi-Byte Character Set
The Lotus Multi-Byte Character Set (LMBCS) is a proprietary multi-byte character encoding originally conceived in 1988 at Lotus Development Corporation with input from Bob Balaban and others.[1] Created around the same time and addressing some of the same problems, LMBCS could be viewed as parallel development and possible alternative to Unicode.[1] For maximum compatibility, later issues of LMBCS incorporate UTF-16 as a subset.[2][3]
Commercially, LMBCS was first introduced as the default character set of Lotus 1-2-3 Release 3 for DOS in March 1989[1][4] and Lotus 1-2-3/G Release 1 for OS/2[1] in 1990 replacing the 8-bit Lotus International Character Set (LICS) and ASCII used in earlier DOS-only versions of Lotus 1-2-3 and Symphony.[5] LMBCS is also used in IBM/Lotus SmartSuite, Notes and Domino,[1] as well as in a number of third-party products.
LMBCS encodes the characters required for languages using the Latin,[6] Arabic, Hebrew, Greek and Cyrillic[6] scripts, the Thai, Chinese, Japanese[6] and Korean writing systems, and technical symbols.
Encodings
Technically, LMBCS is a lead-byte encoding where code point 00hex as well as code points 20hex (32) to 7Fhex (127) are identical to ASCII[1] (as well as to LICS).[5]
Code point 00hex is always treated as NUL character to ensure maximum code compatibility with existing software libraries dealing with null-terminated strings[1] in many programming languages such as C.[nb 1]
Code points 01hex to 1Fhex, which serve as control codes in ASCII, are used as lead bytes to switch the definition of code points above 7Fhex between several code groups (similar to code pages) and at the same time determine either a single- or multi-byte nature for the corresponding code group.[1]
For example, code group 1 (with group byte 01hex)[1] is almost identical to the SBCS code page 850, whereas code group 16 (with group byte 10hex)[1] is similar to the Japanese MBCS code page 932. Multi-byte characters can thus occupy two or three bytes.[7][6]
In canonical LMBCS, each character starts with its group byte.[1] To reduce the length, in optimized or compressed LMBCS a default code group or optimization group code can be defined on a per application or process basis (ideally chosen according to the highest likelihood of occurrence)[1] and must be communicated to the interpreting code in some way (f.e. by specifying the corresponding "LMBCS-n" name).[8] Thereby, the group byte can be omitted for these characters.[1] Lotus 1-2-3 retrieves the optimization group code from the file header of the corresponding source file,[7] whereas for Lotus Notes the optimization group code is fixed to be always 01hex.[2][7]

Notes
- ↑ Lotus 1-2-3 Release 3.0 for DOS and newer versions are written in C.
- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 According to the documentation this code point is not supported by Lotus 1-2-3 Release 3.1+ for DOS and OS/2 and earlier.
- 1 2 3 4 5 6 7 8 9 For compatibility with Lotus 1-2-3 Release 5.0.
- 1 2 LMBCS group 1 code points 0162hex (LATIN SMALL LIGATURE FI) and 0163hex (LATIN SMALL LIGATURE FL) originally overlapped with Microsoft's Private Use Area (PUA) but were later redefined according to new Unicode definitions.
- ↑ Unicode does not define a glyph for the crown currency symbol (Krone aka "Kr"), therefore this points to F8FBhex in the Unicode Private Use Area (PUA).
- 1 2 According to the documentation code points 1 to 127 in this group are not supported by Lotus 1-2-3 Release 3.1+ for DOS and OS/2 and earlier. These versions only supported LMBCS code points 0 to 511, covering group 0 and 1 only.

For optimization purposes, the group byte is omitted in Notes for single-byte values between X'20' and X'FF'. For example, LMBCS is always optimized to group 0x01, which means that any character where the first byte is greater than 0x1F, has an implicit group byte of 0x01.

[…] Notes uses a single character set, the Lotus Multibyte Character Set (LMBCS), to encode all text data used internally by its programs. Whenever Notes first inputs text encoded in a character set other than LMBCS, it translates the text into a LMBCS string, and whenever it must output text in a character set other than LMBCS, it translates the internal LMBCS string into the appropriate character set. Because all text is internally formatted by LMBCS, all text-processing operations […] are done in only one way. LMBCS uses up to three bytes in memory to represent a single text character […]
