-      same way inside of the bitmap; the program assumes every variable-
-      width glyphs to have a width of 15, regardless of the tagged width.
-      If the diacritic is aligned before the glyph, the diacritic itself
-      is always assumed as left-aligned, as this font will swap position
-      of said diacritic and the glyph right before it.
+NOTE: If the diacritics comes before AND after the glyph (e.g. U+103C),
+      "Align before the glyph" must be set too.
+         If glyphs are right or centre aligned, they must be aligned in
+      the same way inside of the bitmap; the program assumes every vari-
+      able-width glyphs to have a width of 15, regardless of the tagged
+      width.
+         If the diacritic is aligned before the glyph, the diacritic it-
+      self is always assumed as left-aligned, as this font will exchange
+      position of said diacritic and the glyph right before it.
