Éséka vs Mbé

Informations

Mojibake (Wen Zi Hua ke, IPA: [modzibake]), is the uncodified text result of text being decoded with an unintended character encoding. This is the systematic replacement of symbols by completely unrelated symbols, often using a different writing system. In places where the binary representation has been invalidated, this display can include the generic replacement character (). Multiple consecutive symbols can be substituted if the binary code is used in both encodings. This could be due to different constant length encodings (e.

g. Asian 16-bit encoders vs European eight-bit encoders) or variable length encoders (such as UTF-8 or UTF-16). Failed rendering of glyphs is caused by missing fonts, or missing glyphs within a font. This is a separate issue and should not be confused with mojibake. Blocks with the code point displayed as hexadecimal, or using the generic substitute character are signs of failed rendering. These replacements are valid, and the result of the correct error handling by software.

Informations

In computer science, group coded recording or group code recording (GCR) refers to several distinct but related encoding methods for representing data on magnetic media. The first, used in 6250 bpi magnetic tape since 1973, is an error-correcting code combined with a run-length limited (RLL) encoding scheme, belonging into the group of modulation codes.

The others are different mainframe hard disk as well as floppy disk encoding methods used in some microcomputers until the late 1980s. GCR is a modified form of a NRZI code, but necessarily with a higher transition density.
