KOReader Apostrophe Spacing Issue (Extra Spaces After Apostrophes)

SOLUTION: KOReader Apostrophe Spacing Issue (Extra Spaces After Apostrophes)

For anyone encountering the irritating apostrophe spacing bug where KOReader adds huge gaps after apostrophes (like "don' t" instead of "don't"), here's the fix that worked for me:

The Problem: Certain publisher-embedded fonts contain incorrect character spacing metrics that cause excessive whitespace after apostrophes.
The Solution:

Open your EPUB in KOReader
Tap the top of the screen to access the settings menu
Select the second icon (looks like an A4/letter page symbol)
Navigate to: Style Tweaks → Text → Font Size And Families
Enable "Ignore Publisher font families"

The apostrophe spacing should immediately correct itself.

Optional: You can also enable "Ignore publisher font sizes" for more consistent typography, though results may vary depending on your preferences.

My setup: KOReader 2025.04 on Kobo Libra 2

Note: Unlike older versions, my KOReader installation didn't have separate "Embedded Style" or "Embedded fonts" toggles - the "Ignore Publisher font families" option handles this directly.

Hope this saves someone else the frustration when lookin gat old threads!
