This is the Adobe bitmap font, Helvetica. The font name has been changed to "Helv" in the source files in order to not be used in applications when "Helvetica" is requested. This Adobe version of the Helvetica font is bitmap and does not look good in web pages and other applications.

The hinting of some fonts may not look right. It is usually because of the size. For example, trying setting the font to 12 in Terminator.
