The Font Validator can be useful to developers creating or modifying fonts, or to developers who are creating tools to generate valid fonts. The Validator performs tests of 'static' data as well as tests for run-time errors.  Microsoft Font Validator The Validator identifies 'static' errors in a font by evaluating the font file and its component tables for their structural adherence to the spec, as well as for encoding inconsistencies within the font, errors with glyph contours, and out-of-range and unlikely values. The Validator performs detailed checks of run-time errors (invalid instructions, stack overflow, IF without ENDIF, etc.) by rasterizing and hinting glyphs.  Microsoft Font Validator help The Validator generates errors when it finds a problem that may cause the font to either function in an unexpected fashion, or not function at all. The Validator generates warnings when it finds something that is inconsistent with Microsoft recommendations. These inconsistencies may not prevent the font from working with current or previous Windows operating systems, but may compromise the usefulness of the font in the future.
