当你遇到`UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb0 in position 29: invalid start byte`错误时,这通常意味着你尝试以UTF-8编码读取的数据包含了非UTF-8字符,特别是对于位置29的字节0xb0。UTF-8不支持该字节作为开始。
1. 检查文件编码[^1]:确认数据源的实际编码。如果不是UTF-8,可能需要更改解码器。例如,如果文件使用的是GBK编码:
```python
try:
data = open('file.txt', encoding='gbk').read()
except UnicodeDecodeError:
data = open('file.txt', encoding='utf-8-sig').read()
```
2. 使用`chardet`库自动检测编码:
```python
import chardet
with open('file.txt', 'rb') as f:
result = chardet.detect(f.read())
encoding = result['encoding']
data = open('file.txt', encoding=encoding).read()
```
3. 如果是从网络接收数据[^2],确保发送方和接收方使用相同的编码,或者在网络传输中明确指定正确的编码格式:
```python
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(('localhost', 1234))
sock.settimeout(5)
data = sock.recv(1024).decode('utf-8')
```
