SMARTFORMS - Underline issue with blank char.

Hello,

When printing a smartforms blanks characters are not underlined if I use policy HELVE, but it works for A_SIMP.

For example: Text smartforms is printed like Text smartforms

Blanks char are not underlined.

With policy A_SIMP there is no problem, but with HELVE it doesn't works.

How can I solve this issue ?

Is it possible to customize policy ?

Thank you.
