Write a Python program to check that a string contains only a certain set of characters (in this case a-z, A-Z and 0-9).Sample Solution: Python Code:import re def is_allowed_specific_char(string): charRe = re.compile(r'[^a-zA-Z0-9]') string = charRe.search(string) return not...

Native侧如何打印char指针 c++创建的(napi_create_object),或者作为参数传下来的js value,如果想持久持有,需要怎么做?以及怎么主动销毁或减少引用计数 在ArkTS层往C++层注册一个object或function,C++层可以按需往这个回调上进行扔消息同步到上层应用么,请提供示例?在注册object或function时,napi_env是否可以被长时持...

Nothing wrong with it, but I'm not sure how useful it is, it might be in the future if we force UTF-8 conversions to work only on char8_t literals, but currently it won't catch if non-ASCII string is directly converted to the String as ASCII. Yes, this PR is more of a sanity...
