Windows-1257 (Windows Baltic) is an 8-bit, single-byte extended ASCII code page used to support the Estonian (which also used in Windows-1252), 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, Slovene, 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.
The following table shows Windows-1257. Each character is shown with its Unicode equivalent in the tooltip.
