Text encoding maps abstract characters to numeric codes and ultimately to bytes.

supported

Software decodes bytes according to a chosen character encoding, operates on text abstractions, and re-encodes when storing or transmitting.

supported

Mojibake, replacement characters, incorrect string length, and normalization mismatches demonstrate what happens when software confuses bytes, code points, or user-perceived characters.
