# Hidden Characters

 * I have to following code that does not parse:
    `$$T_{aussen} \approx 273^\circ
   K + 25^\circ C \approx 300^\circ K$$`
 * The “same” code does parse:
    `$$T_{aussen} \approx 273^\circ K + 25^\circ C \
   approx 300^\circ K$$`
 * The problem seems to be hidden characters. If you look at the url sent to the
   server you see a difference:

 * %80%84 are the bad once. Other characters producing the same problem are %E2 
   and %C2.
 * I don’t know how to handle this. Some times the characters get added by simply
   copying the code from one place in the text to an other.
 * Any ideas?
 * Thanks!!!
