Windows-1257 (Windows Baltic) is an 8-bit, single-byte extended ASCII code page used to support the Estonian, Latvian and Lithuanian languages under Microsoft Windows. In Lithuania, it is standardised as LST 1590-3, alongside a modified variant named LST 1590-4.[1][2]
The label Windows-1257 was registered with the IANA in 1996, citing a publication of the specification in 1995 and inclusion with pan-European versions of Windows 95.[3] The later ISO 8859-13 encoding (first published in 1998) is similar, but differs in reserving the range 0x80–9F for control characters, and accordingly locating certain quotation marks at codepoints 0xA1, 0xA5, 0xB4 and 0xFF instead (the latter two are used for spacing diacritics in Windows-1257). Windows-1257 is not compatible with the older ISO 8859-4 and ISO 8859-10 encodings. For the letters of the Estonian alphabet, Windows-1257 is compatible with IBM-922.
IBM uses code page 1257 (CCSID 1257, euro sign extended CCSID 5353, and the further extended CCSID 9449) for Windows-1257.[4][5][6][7]
As with many other code pages, the languages supported in this code page can be supported in other code pages. The Estonian language can be written with Windows-1252. It is possible, but unusual, to write Polish, Swedish, Finnish, Norwegian, Danish and German using this code page. The German specific characters will be identical to those encoded in Windows-1252.
Unicode is preferred to Windows-1257 in modern applications.
