+Computer Modern Unicode (CMU Serif) — bundled with StackResume

+
+These TrueType files —

+    CMUSerif-Bold.ttf
+    CMUSerif-Italic.ttf
+    CMUSerif-BoldItalic.ttf
+
+— were generated by converting the OpenType (CFF) "cm-unicode" fonts to
+TrueType outlines (ReportLab cannot embed CFF/PostScript outlines). The glyph
+shapes are unchanged; only the outline format was converted (cubic → quadratic
+Béziers via fontTools/cu2qu).
+
+They are used by the `latex_serif` ("LaTeX") résumé template so the generated
+PDF is typographically identical to a pdfLaTeX-compiled document.

+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded,
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply to any
+document created using the fonts or their derivatives.
