title: In php, my html prints out with � all over the place - is there a fix?
body: <p>Hello I have two php file. One of them builds a report, the second contains the language text. When it prints, it keeps giving me the � special character everywhere, even if I am not using any special characters in my code. Why is that and how can I get rid of those?</p>

  <p>Glossary
  Arteries</p>
  
  <p>Arteries�are�blood vessels�that carry blood�away from the�heart. All arteries, with the exception of the�pulmonary�and�umbilical arteries, carry oxygenated blood. The�circulatory system�is extremely important for sustaining�life. Its proper functioning is responsible for the delivery of�oxygen and�nutrients�to all cells, as well as the removal of�carbon dioxide�and waste products, maintenance of optimum�pH, and the mobility of the elements, proteins and cells of the�immune system. In�developed countries, the two leading causes of�death, myocardial infarction�and�stroke�each may directly result from an arterial system that has been slowly and progressively compromised by years of deterioration.
  Autoimmunity</p>
  
  <p>Autoimmunity�is the failure of an organism to recognize its own constituent parts as�self, which allows an immune response against its own cells and tissues. Any disease that results from such an aberrant immune response is termed an�autoimmune disease.�
  Basal cell carcinoma</p>
  
  <p>Basal cell carcinoma�is the most common type of�skin cancer. It rarely�metastasizes�or kills, but it is still considered�malignant because it can cause significant destruction and disfigurement�by invading surrounding tissues. Statistically, approximately 3 out of 10 Caucasians develop a basal cell cancer within their lifetime. In 80 percent of all cases, basal cell cancers are found on the head and neck.�There appears to be an increase in the incidence of basal cell cancer of the trunk in recent years.</p>
