Code page 850 (also known as CP 850, IBM 00850,〔 OEM 850,〔 MS-DOS Latin 1〔) is a code page used under MS-DOS in Western Europe. English DOS systems also sometimes use code page 850, although code page 437 is generally the default on those. Systems largely replaced code page 850 with, firstly, Windows-1252 (often mislabeled as ISO-8859-1), and later with UCS-2, and finally with UTF-16 (the NT line was natively Unicode from the start, but issues of development tool support and compatibility with Windows 9x kept most applications on the 8-bit code pages). Code page 850 differs from code page 437 in that many of the box drawing characters, Greek letters, and various symbols were replaced with additional Latin letters with diacritics, thus greatly improving support for Western European languages (all characters from ISO 8859-1 are included). At the same time, the changes frequently caused display glitches with programs that made use of the box-drawing characters to display a GUI-like surface in text mode, such as programs using Turbo Pascal. In 1998, code page 858 was derived from this code page by changing code point 213 (D5hex) from dotless i ‹ı› to the euro sign ‹€›.〔 Despite this, IBM's PC DOS 2000, released in 1998, changed their definition of code page 850 to what they called ''modified code page 850'' now including the euro sign at code point 213 instead of adding support for the new code page 858.〔〔〔〔 ==Code page layout== The following table shows code page 850.〔〔 Each character appears with its equivalent Unicode code-point and its decimal code-point. Only the second half of the table (code points 128–255) is shown, the first half (code points 0–127) being the same as ASCII; but code points 1–31 and 127 (00–1Fhex and 7Fhex) have a different interpretation in some circumstances – see code page 437. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「code page 850」の詳細全文を読む スポンサード リンク
