The following is the closest I can get using character map:

Keep in mind that the gaps are not supposed to be there. It's just a formatting error.
the symbol is like this but without the gap:

Resistor symbol looks like this:

what does a resistor in an ampliflyer circuit
resistor
Often we want to easily change a resistor value, so we use a variable resistor. For example, we may want to change the resistor that controls the power sent to a LED, so we can easily make it brighter or dimmer. Often if we use a variable resistor, there is only a very narrow range that is useful. Continuing our example, sometimes we use several LEDs, and we use the variable resistor to set them all to the same brightness. In this case, the resistance range that sets the LED to be twice as bright as the the other LEDs, and the resistance range that sends so much power to the LED that it is permanently destroyed is even less useful. So we add a fixed resistor in series with the variable resistor -- the fixed resistor sets the minimum net resistance, no matter how we turn the knob on the variable resistor. In our example, the addition of the fixed resistor allows us to turn the variable resistor throughout its whole range, and the LED gets brighter and dimmer; without that resistor, a certain range of the knob on the variable resistor would allow so much power to go to the LED that it would be destroyed.

No... Diode block one way... resistor block eitherway.
Scroll down to related links and look at "Symbols for a resistor".
Put the resistor symbol ie zig zag. Then put a crossing line with arrow headed at the top.

An LDR is a Light dependent resistor.
Its a sign of resistor with a tilted arrow.
symbols of fixed resistors
labeled R, a resistor looks like this in a diagram-----/\/\/\/\/\-----add a variable resistor has an arrow superimposed at an angle.The modern symbol is a thin rectangle, with the lead outs shown at the centre of the smaller ends.The old symbol was shown as a Zigzag.
Use the standard resistor symbol and then place an arrow across the resistor. The bottom of the arrow midpoint of the resistor and just below, the tip of the arrow (draw with an arrow head) just above the resistor. This represents the wiper of the variable resistor.

Do not confuse 'resistance' with 'resistor'. 'Resistance' is a quantity, wheras a 'resistor' is a circuit component. In schematic diagrams, the 'rectangular' (European) or 'zig-zag' (US) circuit symbol represents resistance, not a resistor. The circuit symbol, therefore, is used to represent anyresistive device.
The symbol for a wire is simply a line between circuit elements. The symbol for a resistor is a squiggly line. The related link goes directly to a picture of the symbol.
