It's not a big deal but in many languages is not grammar correct to 'capitalize' headers and menu (like in English).
My suggestion is to disable text-transform: capitalize; in default themes or add it as an options. It should depend on language resources not on the theme.
/* Line 23 */
.section-header .title
{
float: left;
color: #009fff;
font-size: 14px;
font-weight: 700;
vertical-align: bottom;
padding-top: 5px;
text-transform: capitalize;
}
