ISO 8859-9, more specifically ISO / IEC 8859-9, also known as Latin -5, is a recently updated in 1999 by the ISO standard for information technology to character encoding with eight bits and the ninth 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 8859-9 96 more ( A016 - FF16 ), for a total of 191 theoretically possible 256 ( = 28). Positions 0016- 1F16 and 7F16, 9F16 are assigned in ISO / IEC 8859, and thus the ISO / IEC 8859-9 no characters. The defined by IANA as ISO -8859 -9 ( 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 8859-9 tried to cover all the letters of the Turkish language. Its predecessor is ISO 8859-3 or ISO 8859-1, the Turkish ( Ğ / ğ, İ / ı, Ş / ş ), Icelandic ( Ð / ð, Ý / ý Þ / þ) replace letters.
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.
