regex - HowTo prevent matching an empty string ('') at the beginning of a string include match within the string -

i trying match name following regex

/^[a-za-zàáâäãåąčćęèéêëėįìíîïłńòóôöõøùúûüųūÿýżźñçčšžÀÁÂÄÃÅĄĆČĖĘÈÉÊËÌÍÎÏĮŁŃÒÓÔÖÕØÙÚÛÜŲŪŸÝŻŹÑßÇŒÆČŠŽ∂ð ,\'\-]+$/ 

this matches following examples:

• tom dooley
• d'agaene-venus
• tom

however, when application starts don't want validator match /''/ string in text input, want match /'/ in body of name in d'agaene above.
