Unicode enables some formatting in plain text using combining characters like U+0332 COMBINING LOW LINE: E̲x̲a̲m̲p̲l̲e̲ ̲o̲f̲ ̲u̲n̲d̲e̲r̲l̲i̲n̲e̲d̲ ̲t̲e̲x̲t̲.

How do I do it automatically, without manually inserting U+0332 after each character?

Preferrably free/open source or online.

    Those underlines and overlines look really ugly... – Thomas Weller Jun 24 '16 at 16:25
  • But they may work even when formatting is otherwise not supported. – Vi. Jun 24 '16 at 16:27

One may need to add additional temporary letters or spaces to workaround non-recognition of patterns.

If one needs reverse transformation, post a comment.
