New commits: commit 23e4291f2545f56432b0a9c4d709048825327bc2 Author: Thomas Freitag <[email protected]> Date: Wed Feb 17 22:59:30 2016 +0100 Check if PDF knows the witdh of 'm' in case of substituted font To check wether the PDF font declaration includes the width of the letter 'm', compare it with the width of code 0. Code 0 is the replacement glyph in a font and has the width of a blank. The width table is initialized with this value, and the blank is always smaller than a 'm'.
