Are databases of SuperMemo 6 compatible with SuperMemo 7?
Databases of SuperMemo 6 are compatible with SuperMemo 7; however, ASCII characters below 32 and above 128 may be defined differently in DOS and Windows environments. Moreover, spaces (char #32) in standard non-fixed Windows fonts have lower width, which may corrupt some mathematical or chemical formulas. You can easily remedy the above problems by means of Tools : Replace strings or REPSTR.EXE included in the SuperMemo Toolkit. The easiest way to remedy DOS and Windows incompatibilities is to use the font Terminal.
