Description Mark Hung 2022-05-29 11:58:12 UTC

Description:
In text grid mode, it is required that there is at most one glyph in a grid cell. The test case shows that characters squeezed because of the following half-width kana characters, because the half-width kana are narrower than kanji glyphs.

Steps to Reproduce:
1. Open the attached text file.
2. Observe the first three glyphs '中中中' in the first line, comparing the to those in the second line.


Actual Results:
Three characters squeeze.

Expected Results:
Only one glyph is allowed in one grid cell.


Reproducible: Always


User Profile Reset: No
