The other day, I was importing a Japanese transcript into LingQ. It was a PDF file.
Unfortunetly, the Japanese characters in the PDF file had spaces in between them.
Ex: 英会話 would be imported as 英 会 話
Not good for looking up words. But I found a solution.
This site deletes the spacing in text.
I simply copied the PDF text into this site, ran the program, and the new text was ready for importing.
