Questions tagged [mongolian-vertical-script]

For issues related to the display and rendering of vertical Mongolian text

Traditional Mongolian script is written from top to bottom and in columns from left to write.

enter image description here

This presents a unique challenge when trying to display text on systems only designed to support left-to-right and right-to-left horizontal text. It is even different than when Chinese or Japanese are written vertically because the Mongolian font glyphs are stored horizontally and must be rotated 90 degrees clockwise.

The letters of traditional Mongolian script also change form based on there position in the word and surrounding context. Thus, there are also various Unicode and rendering issues.

Questions that contain this tag can thus be related to the following programmatic issues specific to Mongolian Vertical Script:

  • Top-to-bottom text direction with left-to-right column text wrapping
  • Unicode rendering
