This question already has an answer here:

I wish to write a pure-text square root symbol, like √. The purpose is to write an instruction as it is displayed on a simple calculator, i.e. something like √(2+3). I am aware of $\sqrt{}$, but I don't want to use this because with an empty argument, the square root-sign is too low compared to the surrounding text. I could fix the position of the symbol using something like $\sqrt{\color{white}{|}}$ (provided I have xcolor loaded) but the result isn't beautiful.

Is there a command to produce the √-symbol (such as we have \$ for $)? Apparently \√ doesn't exist.

Detexify suggests

  • $\surd$, which is exactly a math-mode square root sign without argument.
  • \textsurd (provided the package textcomp) comes close.

I wonder if there is an exact version of √, i.e. as one can use in other text-editors.

    Try $\surd$... – Werner Dec 8 '14 at 14:21
  • Try also $\sqrt{\mathstrut}$ or $\sqrt{\vphantom{5}}$ .... – user11232 Dec 8 '14 at 14:28
  • How about any of the above suggestions with \newcommand\textsqrtsymbol{\mbox{$\sqrt{\mathstrut}$}} where $\sqrt{\mathstrut}$ can be replaced by whatever produces the symbol most to your liking. – A.Ellett Dec 8 '14 at 14:29
  • How you can use the symbol in word processing applications is outside the scope of this site. – egreg Dec 8 '14 at 14:30
  • Hmm, perhaps this is a bad question indeed. Shall I delete it? – Schneider Dec 8 '14 at 14:32

You can type the character directly if you load inputenc with the option utf8x.

    Thanks. Is there any reason why one would not want to load inputenc with utf8x, i.e. does it conflict with other features? – Schneider Dec 8 '14 at 21:48
