    The difference between a "normal" space character (U+0020) and a "non-breaking" space character (U+00A0) is that when rendered for display in HTML for example, or in some text editors there is a difference As for the word wrap when a line break can occur, for example, if you want the string 20 gradosto remain on a single line, that is, the wrap of the text does not cause it to be displayed as

    20

    grados

    in case the text exceeds the width of the screen after the 20y that leads gradosto the next line.

    With the use of the "non-breaking space" character (U+00A0) to separate the words, it will be achieved that when the screen width is exceeded, the chain will jump

    20 grados

    complete to the next line and do not break across 2 lines of text.

    This is the basic difference between ASCII 160 and 32, as you mention in the title of your question.

    In the comparison you are doing the result is false because the space characters are different after the "9". For the comparison to result in true, as @Kilbunny's comment says, you can replace the "non-breaking" space with whitespace before comparing the strings.
