How to choose a charset
Use more characters when your image has many brightness levels. Use fewer characters when the source is simple, such as a logo or silhouette. If the output looks noisy, reduce the charset complexity and raise contrast.
Dark-to-light direction
Most converters expect characters from darkest to lightest. If your output looks inverted, enable invert brightness or reverse the ramp.
