Code Golf: Build Me an Arc

Challenge

The shortest program by character count that accepts standard input of the form X-Y R, with the following guarantees:

• R is a non-negative decimal number less than or equal to 8
• X and Y are non-negative angles given in decimal as multiples of 45° (0, 45, 90, 135, etc.)
• X is less than Y
• Y is not 360 if X is 0

And produces on standard output an ASCII "arc" from the starting angle X to the ending angle Y of radius R, where:

• The vertex of the arc is represented by o
• Angles of 0 and 180 are represented by -
• Angles of 45 and 225 are represented by /
• Angles of 90 and 270 are represented by |
• Angles of 135 and 315 are represented by \
• The polygonal area enclosed by the two lines is filled with a non-whitespace character.

The program is not required to produce meaningful output if given invalid input. Solutions in any language are allowed, except of course a language written specifically for this challenge, or one that makes unfair use of an external utility. Extraneous horizontal and vertical whitespace is allowed in the output provided that the format of the output remains correct.

Happy golfing!
