The * OEM character set is system dependent. * * In general OEM, as opposed to ANSI (i.e., 'cp1252'), denotes the * second default codepage that most international versions of Windows * have. It is one of the OEM codepages from * * https://docs.microsoft.com/en-us/windows/desktop/intl/code-page-identifiers * , * * and is used for the 'DOS boxes', to support legacy applications.
