GOST 10859

From Wikipedia, the free encyclopedia

In 1964 the GOST standards body of the Soviet Union defined the standard for encoding data. This standard allowed a variable character size - depending on the type of data being encoded.

GOST 10859 only allowed uppercase characters. Subsequent Soviet standards included lowercase, eg:

1. GOST 13052
2. GOST 19768/74
3. GOST 19768/87

All but one of these characters are now available in unicode, with the exception being the "lower 10" character - "₁₀" (proposed for inclusion as "decimal exponent symbol" [1]) - which was used to express real numbers in Scientific notation. For example: 6.0221415₁₀23.

The "₁₀" character was also part of the ALGOL programming language specifications, and was also incorporated into the then German character encoding standard ALCOR. GOST 10859 also included numerous other non-ASCII characters/symbols useful to ALGOL programmers, eg: ∨, ∧, ⊃, ≡, ¬, ≠, ↑, ↓, ×, ÷, ≤, ≥, ° & ∅. c.f. ALGOL operators[2].

The "␡" character served the same function as the "␡" in 7-bit ASCII.
