 #### Note
-1. There is one more mismatch but it seems it is OK. U+FF1B FULLWIDTH SEMICOLON has UAX 50 value "Tr", and AJ1 is "U". According to Koji Ishii, the "U" orientation is allowed for U+FF1B. The "Table 2. Glyph Changes for Vertical Orientation" in UAX 50 shows both upright and rotated glyphs. As it is not clear from the document, probably it should be improved.

 2. As DOUBLE VERTICAL LINE is a separator, "R" would be the natural expectation. c.f. 句読点、記号・符号活用辞典 (punctuation dictionary) by Shogakkan.
 3. As SCISSORS is emoji-like, "U" would be the natural expectation.
 4. As WAVY DASH is a dash, "R" would be the natural expectation.
