Hinting
575
We can, however, use only one double link, then link the two stems
together with a single link with a rounded distance and set the width of the
right stem with a single link connected to the stem:
The rounded distance of the single links cannot be less than one pixel, so
we will always have some white space between the stems.
To complete the hinting of this character we have to add a rounded single
link to the right sidebearing point to make sure that the white space
between our character and the next character does not disappear.
