Python 3.5+codecsfunction

codecs.namereplace_errors()

error handlers

The 'namereplace' error handler: replaces an unencodable character with its Unicode name as \N{...}. It works only for encoding.

Syntax

codecs.namereplace_errors(exception)

The most human-readable option: a log shows \N{EURO SIGN} instead of \u20ac. The form matches Python string-literal syntax, so the result can be pasted into code. The cost is length: every character turns into dozens of bytes. Added in 3.5; like xmlcharrefreplace, it raises TypeError when decoding.

Examples

print('5€'.encode('ascii', 'namereplace'))  # → b'5\\N{EURO SIGN}'
print('5\N{EURO SIGN}')  # → 5€
