Claudine/fix normalization and house cleaning (#3843)

* remove  normalization in  glyph filter

remove glyph normalization gui/lettering/main_panel, as it  breaks the glyph filtering

remove some spelling mistake in the comments, correct some  comment

if a glyph from the  svg font file is a non chasing mark (like combining accent, or cedilla) the inkscape label of the  corresponding glyph  group created by lettering_font_sample  was empty or unreadable, make it  visible . Same in the line label.

and although it is not related
correct one glyph in malika font

* correct warning in  lettering_font_sample

do  the warnings correctly when there is somethng wrong  with the glyph list in the font.json gile

* Update lettering_font_sample.py

fix a typo
