C # The Unicode text empty row remover

C # The Unicode text empty row remover

When a webpage saves text, there are often many blank lines, which are inconvenient for programming and other applications. The original format is inherited using word, and there are too many commands using other editing tools, therefore, we have compiled such an empty text row eliminator. It can be reduced to the tray icon, which is convenient to use.
Note: Text Files must first be in unicode format.
