To elaborate on the earlier point about Illustrator from amelius. Illustrator's stroke control is a touch more advanced than most people are aware in that there is full control over the width of the stroke at any point on the line and that includes the ability to independently adjust the width on either side of the path. That's especially useful for emulating handwork or script without forcing the object into a less editable format such as a filled shape. To visualise this, see this graphic: https://imgur.com/a/303dgSf https://imgur.com/a/303dgSf The black thin line is a basic stroke to visualise the path. The light blue area is the stroke with edits to the stroke width showing how each side of the path can be controlled independently. I have kept the tool selection active such that a wireframe overlay is visible to help demonstrate how the stroke width is different on either side of the line. The last area in the graphic is the pink area. The pink is another stroke applied to the same path. In fact all 3 strokes you see are all attached to one path. Illustrator allows a path to carry multiple strokes, and those stroke profiles be independent from one another. Side note: This stroke-width information can then be applied to other strokes, and also saved for later use. (Handy if you want a custom swash pack.)
