The marks are drawn once for each typographic character unit. However, emphasis marks are not drawn for:

Word separators or other characters that belong to the Unicode separator classes (Z*). (But note that emphasis marks are drawn for a space that combines with any combining characters.)
Punctuation--specifically, any characters that belong to the Unicode P* general category and do not NFKD normalize [UAX15] to any of the following symbols:
#       U+0023  NUMBER SIGN
%       U+0025  PERCENT SIGN
‰       U+2030  PER MILLE SIGN
‱       U+2031  PER TEN THOUSAND SIGN
٪       U+066A  ARABIC PERCENT SIGN
؉       U+0609  ARABIC-INDIC PER MILLE SIGN
؊       U+060A  ARABIC-INDIC PER TEN THOUSAND SIGN
