Like codepage 437, it aligns with

diacritics and other symbols. It differs from code page 437 in using other dingbats at code points 0–31, in exchanging the box-drawing characters 176–223 for international characters and other symbols, and exchanging code point 236 with the symbol for line integral. However, GEM is more similar to code page 865
, because the codepoints of Ø and ø match the codepoints in that codepage.

A slight adaptation for

character set, it has code points 0-31, 127, and 218-255 empty, and has swapped ¢ and ø and has also swapped ¥ and Ø (to match code page 437 more).

The GEM-derived file manager

DOSSHELL replacement, does not use the GEM character set, but loads its display fonts from DOS .CPI files[1][2][3][4][5][6] depending on the system's current code page
.

Character set

The following table shows the GEM character set. Each character is shown with a potential Unicode equivalent, although some codes do not have a unique Unicode equivalent; the correct choice may depend upon context.

  1. ^
    GEM AES user interface elements such as icons for closing, resizing and maximizing windows
    .
  2. ^ a b Code point 20 (1416) is an unfilled paragraph sign, while code point 188 (BC16) is a filled paragraph sign. This distinction does not exist in Unicode, so both are mapped to U+00B6 PILCROW SIGN here.
  3. micro sign (U+00B5, µ) and the Greek lowercase mu
    (U+03BC, μ).
  4. ohm sign (U+2126, Ω) and the Greek uppercase omega (U+03A9, Ω). (Unicode considers the ohm sign to be equivalent to uppercase omega, and suggests that the latter be used in both contexts.[10]
    )
  5. ^ 235 (EBhex) is the Greek lowercase delta (U+03B4, δ), but it has also been used as a surrogate for the Icelandic lowercase eth (U+00F0, ð) and the partial derivative sign (U+2202, ∂).
