Windows-1257(Windows Baltic) is an8-bit,single-byteextended ASCIIcode pageused to support theEstonian(which also used inWindows-1252),LatvianandLithuanianlanguages underMicrosoft Windows.In Lithuania, it is standardised asLST 1590-3,alongside a modified variant namedLST 1590-4.[1][2]

The labelWindows-1257was registered with theIANAin 1996, citing a publication of the specification in 1995 and inclusion with pan-European versions ofWindows 95.[3]The laterISO 8859-13encoding (first published in 1998) is similar, but differs in reserving the range0x80–9F forcontrol characters,and accordingly locating certainquotation marksat codepoints 0xA1, 0xA5, 0xB4 and 0xFF instead (the latter two are used for spacingdiacriticsin Windows-1257). Windows-1257 is not compatible with the olderISO 8859-4andISO 8859-10encodings. For the letters of theEstonian alphabet,Windows-1257 is compatible withIBM-922.

IBMuses code page 1257 (CCSID1257,euro signextended 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 withWindows-1252.It is possible, but unusual, to writePolish,Slovene,Swedish,Finnish,Norwegian,DanishandGermanusing this code page. The German specific characters will be identical to those encoded in Windows-1252.

Unicodeis preferred to Windows-1257 in modern applications.
