U+303B VERTICAL IDEOGRAPHIC ITERATION MARK

[Wil Tan]

I think the following should be DISALLOWED:

U+3031: Lm: VERTICAL KANA REPEAT MARK
U+3032: Lm: VERTICAL KANA REPEAT WITH VOICED SOUND MARK
U+3033: Lm: VERTICAL KANA REPEAT MARK UPPER HALF
U+3034: Lm: VERTICAL KANA REPEAT WITH VOICED SOUND MARK UPPER HALF
U+3035: Lm: VERTICAL KANA REPEAT MARK LOWER HALF
U+303B: Lm: VERTICAL IDEOGRAPHIC ITERATION MARK

Mainly because U+3033 looks like protocol character (forward slash)
and thus harmful IMO. Since this is a group of characters with related
usage, and that Yoneya-san, Martin Dürst and John suggested that they
should be disallowed:
