White spaces are deleted between two template field tags

When in my source I have two fields tags separated by a simple white space
<span class="jobtxt"><template:field name="town"/> <template:field name="country"/></span>

the two values generated in the HTML are not separated by a space, I'm forced to put a sign   to preserve the space which is not a normal integration process.

In the same template if I test directly with values (jahia is supposed to return a value when processing a field tag
<span class="jobtxt">valeur1 valeur2</span> for example
the html generated is OK with a space between each word. so it's not a css or browser problem (I've tested several times and with several combinations of classes and html tags to be sure)
