Degree Symbol Display

Dear all,

I'm trying to display the degree symbol (the one used for temperature or latitude/longitude coordinates).

I tried to use 167.chr , but the output on the website is '?'.

Code: degrees = [number_with_precision(degrees, precision=0), 167.chr, " ", number_with_precision(minutes, precision=0), "' ", number_with_precision(decimal_seconds, precision=2), '"']

HTML Output: 37? 32' 55.51"

Any ideas ?

Thanks,

I don't know where you got 167 from (perhaps you meant 176?). By default, Rails output is UTF-8. The Unicode code point for the degree sign is 0x00B0, which is the UTF-8 sequence:

   "\xC2\xB0"

As mentioned, you can also use the HTML entity °
