Description


This unit implements the locale support for Ultibo and provides the code page support for the WideStringManager/UnicodeStringManager interface for the RTL.

This unit provides compatible implementations of the following functions:

  • ConvertDefaultLocale
  • EnumCodePagesProc
  • EnumLocalesProc
  • EnumTimeFormats
  • GetCPInfo
  • GetNumberFormat
  • GetSystemDefaultLangID
  • GetUserDefaultLangID
  • IsValidLocale
  • GetConsoleOutputCP
  • EnumCalendarInfo
  • EnumDateFormats
  • EnumSystemCodePages
  • EnumTimeFormatsProc
  • GetCurrencyFormat
  • GetLocaleInfo
  • GetSystemDefaultLCID
  • GetUserDefaultLCID
  • SetLocaleInfo
  • SetConsoleCP
  • EnumCalendarInfoProc
  • EnumDateFormatsProc
  • EnumSystemLocales
  • GetACP
  • GetDateFormat
  • GetOEMCP
  • GetTimeFormat
  • IsValidCodePage
  • GetConsoleCP
  • SetConsoleOutputCP


The following functions are implemented by the Threads unit:

  • GetThreadLocale (ThreadGetLocale) (GetThreadLocale is exposed in the Ultibo unit)
  • SetThreadLocale (ThreadSetLocale) (SetThreadLocale is exposed in the Ultibo unit)

Most of the above are currently not implemented.


OEM Code Page defaults to 437 (OEM United States)

ANSI Code Page defaults to 1252 (ANSI Latin 1; Western European (Windows))
