Mongolian lists & counters #55
Description
Here is some information from Prof. Liang Jinbao from Inner Mongolia University of Technology. We might want to consider adding some of it to § 6.4 Lists, counters, etc.
Mongolian usually uses ASCII digits, however there is a set of Mongolian digits. The traditional Mongolian digits are no longer known to anyone except scholars. They are not seen in modern printed books, but only occasionally in ancient books and documents. Not sure whether Manchu and Xibe use these digits. When displaying a list on a modern Mongolian web page, if the number is displayed like this, people will think it is garbled. In VerticalOrientation.txt, the Mongolian digits are 'R' (characters which are displayed sideways, rotated 90 degrees clockwise compared to the code charts).
ASCII digits in list markers should be rotated, but I have also seen many that are not rotated. This may be because the software does not support it and there is no choice. If unrotated, longer numbers with two or three digits risk overflowing their allotted space.
The circled digits ① ② ③ doesn't exist traditionally, and the properties in the typesetting software are the same as Chinese characters, so it can only stay unrotated.
Here are some samples:
