text-spacing-trim
A modern property that helps manage the spacing between characters in CJK (Chinese, Japanese, Korean) typography. It specifically handles how 'half-width' punctuation and characters should be spaced to keep the layout looking clean.
It is documented as part of the CSS Text specification. This is an experimental technology. The syntax and behavior are still subject to change.
