URL: https://github.com/apache/beam/pull/26201
Textio documentation states that only `UTF-8` and `ASCII` encodings are
supported. This is not true because a coder with custom encoding can be passed
in and used to decode the text.
Example:
```
class VariableCodecCoder(Coder):
def __init__(self, codec):
self._codec = codec
def encode(self, value):
return value.encode(self._codec)
def decode(self, value):
return value.decode(self._codec)
def is_deterministic(self):
return True
def to_type_hint(self):
return str
with beam.Pipeline() as p:
(
p
| beam.io.ReadFromText("a", coder = VariableCodecCoder('cp864'))
| beam.Map(print)
)
```
