c++在无符号字符向量中查找字符

Question

我有以下代码的问题：

message is vector<unsigned char>

vector<unsigned char>::iterator pos = message.begin();
vector<unsigned char>::iterator start = message.begin();
vector<unsigned char>::iterator end = message.end();

pos = find(start, end, ' ');

我收到错误：

error: no matching function for call to ‘find(std::vector<unsigned char>::iterator&, std::vector<unsigned char>::iterator&, char)’
