In pure-python implementation yaml.load cannot read files generated by yaml.dump/safe_dump when allow_unicode=True

"!!python/unicode 'Even just latin in unicode'\n"

In cpython (with yaml with c-extension) yaml.load works with this file.

The only thing more I could hope for is documentation of all these features (other than reading through the code).  Cipto Junaedy Is this in process? Can I help? About  Unit Link Terbaik di Indonesia Commonwealth Life Investra Link

The second issue is that the emitter escapes non-ASCII characters even when all characters are printable (according to 'c-printable' in the YAML spec) when using an encoding (UTF8) that supports such characters. I don't find this as elegant as could be. Instead of the "Fran\xE7ais" output above, I would have hoped for the UTF8-encoded byte string Fran\xc3\xa7ais\n. agen texas poker dan domino online indonesia terpercaya Situs Judi Poker Online Terbaik Terpercaya
