RE: Fullwidth/upright vertical characters in Mongolian

Hi Richard,

> IS IT COMMON TO HAVE 'UPRIGHT' NON-CJKM CHARACTERS IN MONGOLIAN?
In inner Mongolia, as our experience,
1. The half width Latin and digits are commonly written in sideways by default.
2. The CJK and Fullwidth characters (exclude some of the punctuations) are commonly written upright vertical characters in Mongolian vertical text(vertical-lr), 
  Exactly same with CJK vertical mode (vertical-rl).
3. Some of the Fullwidth punctuations (for example 「」、【】、（）、…、－、＝ etc.), need to be written in sideways by default, exactly same in CJK vertical mode.

According to above, it is best to define the vo property and use it on the vertical-lr same as for vertical-rl style. 
Please refer to the SiqinBilige's examples in different mail.

In the URL, http://www.mongolfont.com/mn/computer/history.html
We expected that the circled digits are all displaying in upright here. 
But, chrome displays it sideways, Edge displays it upright, Firefox displays it upright, etc. now.

We can display the Fullwidth characters in vertical-lr mode exactly same with in the vertical-rl mode by default.

But there are some uncommon usage, for example, some halfwidth digits or punctuations, if their length is 1 or 2 characters(2, 1. Or 21, 3c etc) , it will be written as upright in vertical text. More than 3 characters will be written as sideways. This is same with in the Japanese vertical text mode.
I am not sure if it is controlled by the character default property or by the special CSS in Japanese. I think we have same requirement in Mongolian vertical text mode.

Thanks and Best regards,

Jirimutu

Greg, Jirimutu, Badral,

Thanks for your responses!  Let me try to synthesise what i heard here, to check whether i understood correctly, and ask some follow-on questions.  (It would be great if you have examples to hand that you could scan and send, btw.)

ARE FULLWIDTH LATIN CHARACTERS USED IN MONGOLIAN?

Greg has seen full-width punctuation characters. (It would be great if you could give me some examples of what kinds of punctuation
characters.)  I'm assuming that it wouldn't include the fullwidth commas and periods you see in Chinese text but perhaps it includes question marks? Parentheses and brackets?

Jirimutu mentioned what i understood to be counters for lists – is that correct?  If so, that's interesting, since i was going to ask about that specific case.

Badral mentioned that he'd seen full-width Latin + Cyrillic characters. 
The addition of cyrillic here is interesting because there are no fullwidth cyrillic characters in Unicode afaik. Is a font applied to achieve that effect?


IS IT COMMON TO HAVE 'UPRIGHT' NON-CJKM CHARACTERS IN MONGOLIAN?

I should have probably already mentioned that i expect Han characters to be upright in vertical Mongolian text, and that this is produced by default when using CSS styling.  UTR#50 [1] describes the vo property, which indicates which characters appear upright by default, and which are rotated (and in some cases transformed).

I'm hearing, however, that there are occasions where Latin text, and characters such as digits may appear upright, although by default they run down the page on their side.

Jirimutu also mentioned characters such as circled digits, which it seems logical to see upright. 
http://www.mongolfont.com/mn/computer/history.html shows circled digits for list counters, but there is CSS styling to make them display on their side, rather than appear upright (which would be the default for those characters).  So that suggests to me that content authors may want these list counters may appear sideways, rather than upright (which is their natural default according to Unicode properties).

I guess i should probably have asked whether fullwidth characters always stand upright, or whether they can also run down the page on their side.

cheers,
ri
