json 中的编码或 python 中的 yaml 文件是否有意义?

Does the encoding make sense in json or yaml files in python?

我尝试将此词典保存在 json 或 yaml 文件中:

d = {'name': 'María Gómez', 'message': '¡Es una caña atómica!'}
with open(file, 'wt', encoding='iso8859-1') as file:
   json.dump(d, file)

但是,文件内容不在该编码中,非 ascii 字符在 json 或 yaml 文件中转义。因此,我认为编码文件没有意义。或者是否有一些语言或字符的编码对此类文件有意义?

import json
d = {'name': 'María Gómez', 'message': '¡Es una caña atómica!'}
json.dumps(d)
# '{"name": "Mar\u00eda G\u00f3mez", "message": "\u00a1Es una ca\u00f1a at\u00f3mica!"}'
json.dumps(d, ensure_ascii=False)
# '{"name": "María Gómez", "message": "¡Es una caña atómica!"}'

说明(对json.dumpsjson.dump有效):JSON encoder and decoder basic usage:

If ensure_ascii is true (the default), the output is guaranteed to have all incoming non-ASCII characters escaped. If ensure_ascii is false, these characters will be output as-is.
