ISO 8859-`x` to Latin `y` Conversion

ISO 8859-`x`	Latin `y`	Reference

UTF-8 Bit Distribution

Unicode Scalar Value	Byte 1	Byte 2	Byte 3	Byte 4
0 0000 0000 0000 0`abc defg` (0–0x7F)	0`abc defg`
0 0000 0000 0`abc defg hijk` (0x80–0x7FF)	110`a bcde`	10`fg hijk`
0 0000 `abcd efgh ijkl mnop` (0x800–0xD7FF, 0xE000–0xFFFF *)	1110 `abcd`	10`ef ghij`	10`kl mnop`
`a bcde fghi jklm nopq rstu` (0x10000–0x10FFFF)	1111 0`abc`	10`de fghi`	10`jk lmno`	10`pq rstu`

* Scalar values in the range 0xD800–0xDFFF are reserved for surrogate pairs and do not yield valid UTF-8 sequences so abcde should never equal 11011.
