Windows-1257 (Windows Baltic) is a single byte code page used to support the Estonian, Latvian and Lithuanian languages under Microsoft Windows. This code page is similar in layout to ISO 8859-13, but they differ in codepoints A1, A5, B4, FF, and of course in the range 80–9F, which is typically allocated with graphical characters in most single byte Windows code pages. Windows-1257 is not compatible with the older ISO 8859-4 and ISO 8859-10 encodings.
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 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.
