Description Mark Hung 2017-04-08 01:40:02 UTC
Created attachment 132403 [details]
Sample File

1. Tools / Options / LibreOffice Writer / General / Use, uncheck "square page mode"
2. Select "Lines and Chars" in Text Grid tab in Page Style dialog.
3. Set Lines per page to 60, Max base text size to 12pt
4. Set Characters per line to 60, Characters width to 8pt
5. Enter some Chinese with text less than 10 pt. It even overlap when text size is 6pt.

According to ODF1.2, 20.301 style:layout-grid-mode Within a layout cell, no more than one Asian [UNICODE] character is displayed. An Asian character that does not fit into a single layout cell is displayed centered into as many layout cells as required. Non Asian text is centered within as many cells as required.

According to ODF1.2, 20.305 style:layout-grid-snap-to
The style:layout-grid-snap-to attribute specifies whether the text is snapped to the grid or not. It is evaluated only if the style:layout-grid-mode attribute has the value both and the style:layout-grid-standard-mode attribute has the value true.

Microsoft Word has similar feature, that it can select "Lines and Chars", except it specifies character distance and line distance instead of Max base text size and Character width. So characters are always layout in fix distance.

Comment 2 Mark Hung 2017-04-15 12:22:22 UTC
Note for what I have found
1. It is not clear what it should be when "Snap to Char" is unchecked,
the actual formatting behavior is unspecified or ambiguous in ODF1.2, 20.305 of ODF 1.2.

2. Writer formats this way: it offset each Chinese character by ( grid width - font height of default style  ). It may be negative, that's why characters cluttered or overlapped.

3. Imitating what Microsoft Word do is preferred, but Writer ( or ODF1.2 ) lacks of the necessary attribute, character distance, but may be devise from number of characters per line.
Comment 3 Mark Hung 2017-04-15 12:57:44 UTC
Ok, it seems ( grid width - font height of default style  ) is what Microsoft Word does, except it do not use negative value.
