Not every check is necessary some apply only to specific scripts or languages (such as those in the “CID” tab), while others apply only to specific, optional font features (such as the checks in the references tab). The problems that the Find Problems tool can look for are sorted into these eight groups: When you click the OK button, the tool will examine all of the selected glyphs, and report any problems it finds in a dialog box. You can select which problems you are interested in looking for by checking the checkbox next to each, and in some cases providing a numeric value to check the font against. The tool presents you with an assortment of potential problems in eight separate tabs. You must first select one or more glyphs - either from the font view, the outline view, or the metrics view - then open the Find Problems tool. The first tool is called Find Problems, and is found under the Element menu. Validating your font to eliminate these errors will thus not only ensure that it can be installed and enjoyed by users, but also that the finished project exhibits polish. Finally, there are stylistic errors that are not technically incorrect, but that you will still want to repair - such as lines that are intended to be perfectly horizontal or vertical, but are accidentally slightly off-kilter.įontForge offers tools that you can use to locate (and, in many cases, repair) all three categories of problems. An example of this type of issue is that all of the points on a curve should have coordinates that are integers.
The various font file formats also expect glyphs to adhere to certain rules that simplify placing the text on screen, and fonts that break the rules can cause unexpected problems. For example, curves that intersect themselves will not render correctly because they do not have a “inside” and “outside”. Fonts can have technical errors that prevent them from working or displaying correctly.

In a perfect world, your font would be ready to build and install on any modern computer without any special effort, but reality is messier - particularly during the design process.
