I've combined the data from Eric's proposed Unicode property [1] with
Koji's table version of the Appendix C algorithm [2], using Eric's
symbols in order to highlight where differences exist.  The full table
is here:

http://lists.w3.org/Archives/Public/www-archive/2011Sep/att-0008/combinedvalues.txt

The columns are:

  Unicode codepoint
  Orientation category, based on Eric Muller's Strawman proposal for UTR #50: Unicode Properties for Vertical Text Layout [1]
  Orientation category, based on Koji Ishii's proposed Appendix C Vertical Typesetting Synthesis [2]

I switched Koji's data to use Eric's symbols (e.g. S and U for
sideways and upright) and added 'UF' to indicate Koji's "use-font"
category.  This category is "upright using vertical font settings if
available or sideways if they are not" [3], where "vertical font
settings" are effectively whether the font contains *any* vertical
metrics or not.

For comparison I've listed below the Unicode blocks where differences
exist between the two proposals.

Blocks containing characters for which the Appendix C rules imply
upright while the proposed Unicode property value would be sideways:

  2FF0..2FFF; Ideographic Description Characters
  FE50..FE6F; Small Form Variants
  
Blocks containing characters for which the Appendix C rules imply
sideways while the proposed Unicode property value would be upright:

  2150..218F; Number Forms
  2190..21FF; Arrows
  2200..22FF; Mathematical Operators
  2300..23FF; Miscellaneous Technical
  2500..257F; Box Drawing
  2580..259F; Block Elements
  25A0..25FF; Geometric Shapes
  2600..26FF; Miscellaneous Symbols
  2700..27BF; Dingbats
  2900..297F; Supplemental Arrows-B
  2980..29FF; Miscellaneous Mathematical Symbols-B
  2B00..2BFF; Miscellaneous Symbols and Arrows

Blocks containing characters labeled as "use font" by Appendix C rules:

  0000..007F; Basic Latin
  0080..00FF; Latin-1 Supplement
  2000..206F; General Punctuation
  2070..209F; Superscripts and Subscripts
  2150..218F; Number Forms
  3000..303F; CJK Symbols and Punctuation
  30A0..30FF; Katakana
  FE10..FE1F; Vertical Forms
  FE30..FE4F; CJK Compatibility Forms
  FE50..FE6F; Small Form Variants
  FF00..FFEF; Halfwidth and Fullwidth Forms
