Python読み取りファイルエラー:UnicodeEncodeError:'latin-1'codec can't encode character

# UnicodeEncodeError: 'latin-1' codec can't encode character
例:

file = open("xxx.txt","r",encoding="utf-8")

for line in file:
    print(line)

UnicodeEncodeError: 'latin-1' codec can't encode character

変更方法:

file = open("xxx.txt","r",encoding="utf-8")

for line in file:
    line=line.encode("utf-8").decode("latin1")
    print(line)

また、pythonのデフォルト符号化はlatin 1であるため
環境変数を変更できます.

export PYTHONIOENCODING=utf-8
