ISO 8859-7, more specifically ISO / IEC 8859-7 also known as Greek, is a recently updated in 2003 by the ISO standard for information technology to character encoding with eight bits and the seventh part of the family of standards ISO / IEC 8859th
The encodable with seven -bit US-ASCII characters correspond with leading zero bits. In addition to the 95 displayable ASCII characters (2016 - 7E16 ) codes ISO 8859-7 93 more ( A016 - AD16, AF16 - D116, D316 - FE16 ), for a total of 188 theoretically possible 256 ( = 28). Positions 0016- 1F16 and 7F16, 9F16 are assigned in ISO / IEC 8859, and thus the ISO / IEC 8859-7 no characters. The defined by IANA as ISO -8859 -7 ( with hyphen) means the combination of the characters of this standard with control characters can not be represented in accordance with ISO / IEC 6429th
ISO 8859-7 contains all the characters of the modern Greek alphabet, some of which are also used in mathematics.
SP (space) at position 2016 is the space, NBSP ( no-break space, even non-breaking space ) to position A016 is the protected space and SHY ( soft hyphen ) at position AD16 is the conditional hyphen that normally only at the end of the line is visible.
