Fix memory corruption in console selection
Fix an off-by-two memory error in console selection. The loop below goes from sel_start to sel_end (inclusive), so it writes one more character. This one more character was added to the allocated size (+1), but it was not multiplied by an UTF-8 multiplier. This patch fixes a memory corruption when UTF-8 console is used and the user selects a few characters, all of them 3-byte in UTF-8 (for example a frame line). When memory redzones are enabled, a redzone corruption is reported. When they are not enabled, trashing of random memory occurs.
