Weather Monitor parsing bug

In the following code fragment from a provider file I'm writing, I've found a potential problem with fetching temperatures.

Code:

; Dewpoint
; -------------------------------------------------------------------------
[CustomParam4]
name = Dewpoint
unit = C
find0 = "<!-- CURRENT REPORT TABLE -->"
find1 = "<!--Temp-->"
find2 = "Dewpoint:"
delim = "<"

Here's the HTML I'm parsing:

Code:

Dewpoint: 3 &deg;C<br />

Parsing this returns 0°C, but if I remove the Unit = C line from the provider file, I get 3 returned.

I've tried a delim = "&deg" just in case that was the cause, but I still get 0°C!
