fonts/glyph_replacement
Show the effects of glyph substitution in case of glyphs missing in the font.
Load the font and specify a replacement character to be used to output missing glyphs.
Demonstrate various notations to output the Euro sign as U+20AC which is available in the font.
Then, various notations to output the ligature "ffi" are shown, the glyph of which is available in the font.
Output the glyph for an alternative g which is available in the font.
Output the glyph for an alternative s which is not available in the font.
Output the glyph for the ligature "st" which is not available in the font.
Use the "glyphcheck=replace" or "glyphcheck=none" option to determine if the missing glyph will be replaced. Depending on the "glyphcheck" setting the ligature "st" will be replaced by the two characters "s" and "t".
Output the Ohm glyph which is not available in the font. Depending on the "glyphcheck" setting it will be replaced by the Omega character.
