[issue21194] json.dumps with ensure_ascii=False doesn't escape control characters

[akira]

akira added the comment:

json.dumps works correctly in this case.

Both json/application rfc [1] and ecma json standard [2] say:

> All characters may be placed within the quotation marks, except for the characters that must be escaped: quotation mark (U+0022), reverse solidus (U+005C), and the control characters (U+0000 through U+001F).

i.e., only a subset (00-1F) of control characters must be escaped in json string
