My English is not good, sorry

There is a problem with the number of Chinese characters

php version of api interface

UTF-8 string “我是中国人”

rawurlencode(“我是中国人”) = %E6%88%91%E6%98%AF%E4%B8%AD%E5%9B%BD%E4%BA%BA

strlen(‘我是中国人’) = 15 characters in length
strlen(’%E6%88%91%E6%98%AF%E4%B8%AD%E5%9B%BD%E4%BA%BA’) = 45 characters in length

Originally, the Chinese characters I submitted were less than 5000 characters in length
The character length after rawurlencode exceeds 5000

Cause the api interface to return an error with characters exceeding 5000

array(2) {
[“status”]=>
int(412)
[“Error”]=>
string(77) “Text with More than 5000 characters or less than one Character is not allowed”
}
