Windows-1250 is a code page used under Microsoft Windows to represent texts in Central European and Eastern European languages that use the Latin script.
[1] It is also used for Polish (as can Windows-1257), Slovak, Hungarian, Slovene (as can Windows-1257), Serbo-Croatian (Latin script), Romanian (before a 1993 spelling reform) and Albanian (as can Windows-1252).
It may also be used with the German language, though it is missing uppercase ẞ.
However, a few of them are rearranged (unlike Windows-1252, which keeps all printable characters from ISO-8859-1 in the same place).
Most of the rearrangements seem to have been done to keep characters shared with Windows-1252 in the same place but three of the characters moved (Ą, Ľ, ź) cannot be explained this way, since those do not occur in Windows-1252 and could have been put in the same positions as in ISO-8859-2 if ˇ had been put e.g. at 9F.
