Qie Lei

In the default Gutenberg visual editor, multiple spaces you enter are often “merged” and cannot be seen. This plugin solves this problem by converting consecutive spaces to HTML   entities, preserving the visual spacing.
Features: 
– Converts second and subsequent spaces in a sequence to   entities 
– First space remains a regular space (Gutenberg default behavior) 
– Works anywhere in the content, not just at paragraph starts 
– Option to apply to all content or only new content 
– Preserves spaces within pre/code blocks
