The unicode consortium announced the release of utr #50, unicode vertical text layout, today, via twitter and their blog. although i was involved in this unicode technical report to some extent, any congratulatory comments should be directed toward its original and current editors, eric muller and koji ishii (石井宏治), respectively. According to a google engineer who added vertical text layout support to android's classic web browser, she found some issues with the draft version of utr 50 and gave feedback to unicode consortium to address them. The individual katakana characters or cjk unified ideographs that comprise these squared words are assigned the vertical orientation property value u, tu, or tr, and therefore remain upright in vertical layout or have their own vertical form. Up until now, vertical text layout has been challenging for implementers due to the somewhat ambiguous nature of character orientation, and often relied on information that is buried deep within font formats.

Up until now, vertical text layout has been challenging for implementers due to the somewhat ambiguous nature of character orientation, and often relied on information that is buried deep within font formats. As of tot, we have 462 code points in incorrect orientation and 82 inconclusive code points (tests could not validate) out of 24,673 code points, so we could say 98% we're correct. details of this property is defined in the spec above, but in short, this property puts all characters in upright. Utr #50, unicode vertical text layout, is being reissued with minor updates to the text and with a set of data updated to the character repertoire of unicode version 7.0. This is the general approach adopted for unicode processing: most often, characters which are added fall in one of the existing classes, and moving to a new version is just a matter to updating the table that that captures the classification, while the algorithm remains unchanged.
