Feature or enhancement
Proposal:
Most JSON strings consist solely of ASCII characters that don’t require escaping, so adding a fast path for those would make a big difference. In these cases, we can avoid allocating a new string by writing the original string directly:
PyUnicodeWriter_WriteChar(writer, '"') PyUnicodeWriter_WriteStr(writer, pystr) // original string PyUnicodeWriter_WriteChar(writer, '"')
Benchmarks have shown that this roughly 2.2x faster, see PR.
Has this already been discussed elsewhere?
