C strings conversion to Python
For C strings represented as a pair
char *, int, it is to decide whether or not – the string presented as a raw byte string or as a Unicode string.
Byte objects can be built using
To create a Unicode string and is it is known that s points to data encoded as UTF-8, the code given below can be used as –
If s is encoded in some other known encoding, a string using
PyUnicode_Decode() can be made as:
If a wide string needs to be represented as
wchar_t *, len pair. Then are few options as shown below –
- The data from C must be explicitly decoded into a string according to some codec
- Common encodings include ASCII, Latin-1, and UTF-8.
- If you’re encoding is not known, then it is best off to encode the string as bytes instead.
- Python always copies the string data (being provided) when making an object.
- Also, for better reliability, strings should be created using both a pointer and a size rather than relying on NULL-terminated data.
