REVISION SUMMARY
  Group spaces following any non-wide character with the character. This
  allows for rendering ambiguous characters with wide glyphs without
  clipping them. Characters are still clipped when followed by another
  visible character.

TEST PLAN
  - Display: `⛰ ⛩ `
  
  and/or:
  
  - Install Font Awesome or other font with square icons in Private Use Area
  - Pick some icons using KCharSelect or similar tool (or copy this: `     `)
  - Put space after each icon and display them in Konsole
  
  **Actual result:**
  Only left half of icons is rendered
