Original description

What change would like to see?
find(char) doesn't exist, which means you need to wrap a single character as a string.

Why?
The current situation is completely fine with literals - e.g find("$") instead of find('$') - but it can get unnecessarily complex with variables.

For instance you can't write:
char target;
...
find(target);

Instead you need to do something along the lines of:
char target;
...
char buf[2];
buf[0] = target;
buf[1] = 0x00;
find(buf);
