data TextEncoding Source #
A TextEncoding
is a specification of a conversion scheme
between sequences of bytes and sequences of Unicode characters.
For example, UTF-8 is an encoding of Unicode characters into a sequence
of bytes. The TextEncoding
for UTF-8 is utf8
.

InputUnderflow | Stopped because the input contains insufficient available elements, or all of the input sequence has been successfully translated. |
OutputUnderflow | Stopped because the output contains insufficient free elements |
InvalidSequence | Stopped because there are sufficient free elements in the output to output at least one encoded ASCII character, but the input contains an invalid or unrepresentable sequence |
