utf8(::Ptr{UInt8}, length::Int = 1)

utf8(::Ptr{UInt8}, [length])

Create a UTF-8 string from the address of a C (0-terminated) string encoded in UTF-8. A copy is made; the ptr can be safely freed. If length is specified, the string does not have to be 0-terminated.

Examples

julia> utf8("hello")
5-element Array{UInt8,1}:
 0x68
 0x65
 0x6c
 0x6c
 0x6f

Convert a string to a UTF-8 byte array:
```
julia> utf8("julia")
5-element Array{UInt8,1}:
0x6a
0x75
0x6c
0x69
0x61
```
This example converts the string "julia" into a contiguous UTF-8 byte array.
Handle special characters and emojis:
```
julia> utf8("🌍")
4-element Array{UInt8,1}:
0xf0
0x9f
0x8c
0x8d
```
It correctly handles special characters and emojis, converting them to their corresponding UTF-8 representation.
Convert an empty string:
```
julia> utf8("")
0-element Array{UInt8,1}
```
When an empty string is provided, it returns an empty UTF-8 byte array.

Common mistake example:

julia> utf8("hello 😊")
ERROR: ArgumentError: invalid UTF-8 sequence of bytes

In this example, the input string contains an invalid UTF-8 sequence of bytes. Make sure that all characters in the string are valid UTF-8 characters to avoid this error.
