I’m trying to include a degree symbol into my Rails view. If I put the degree symbol (°) straight into .html.erb file, it is displayed by browser in a normal way.
But this symbol should be transferred to view via string. And here the problem begins.
If I put this:
<%= 176.chr %>
into view, or put
.... + 176.chr
into ruby source, I get
incompatible character encodings: UTF-8 and ASCII-8BIT
How to make Rails recognize all views as UTF-8 by default?
You can use special replacement for this symbol in HTML:
°.http://www.w3schools.com/charsets/ref_html_entities_4.asp
You have to put it in HTML, outside the <%= %>. Or use raw helper. Or mark it as html_safe. And by the way, did you try to supply encoding in your chr? Like
176.chr(__ENCODING__)(__ENCODING__here isn’t placeholder, it’s Ruby thing) or 176.chr(Encoding::UTF_8). All these approaches should work.
