With glyph substitution question mark is coming in PDF

[codecracker2014]

In case of glyph substitution occurs for text, glyph array length may change. So limit should be considered while iterating array else null character will get inserted.

Can you write a test for it?

[codecracker2014]

@asturio there is already a test case for FopGlyphProcessor.convertToBytesWithGlyphs method (AdvanceTypographyTest.testTypographySubstitution). Current issue can't be replicated for all fonts, currently it's occurring on calibri font as below.

Can we include calibri font for test case?

Can it be replicated with Liberation-Fonts? They are already in the repo.

Reproducing with Viaoda Libre Font added test case. look 'instruction' has 11 characters but after glyph substitution it is represented with 9 glyphs.

Also added Viaoda Libre(https://fonts.google.com/specimen/Viaoda+Libre) font for tests.
