[nc] Diacritical: Hebrew: ensure combining vowel accents (Nikud) do not touch characters

1. Copy and paste this line into the address field of a Web browser:
data:text/html;charset=UTF-8,<p style="font-family:Ubuntu;font-size:64;"> (shlakh, שְׁלַח)(shalakh, שָׁלַח)</p>

2. Change the "64" to other numbers to test different sizes.

Hebrew uses base characters to represent consonant sounds; the vowels when needed to guide pronunciation are added as combining accents, known as Nikud ('נִקּוּד'). Ideally all text should use full accents, but there is a general tendency outside of scholarly works to only add accents when /needed/ for disambiguation.

For example, 'send' (shlakh, שְׁלַח) and 'sent' (shalakh, שָׁלַח) would both be written simply as שלח (in a manner perhaps analogous to "missing off" accents when writing continental Latin-based European languages on an English- or American-layout keyboard (writing rôle/passé as role/passe).

These combining accents should not touch the main Hebrew characters when drawn, and should be clear and visible separately.

A further form of accent/cantillation is used in addition for Biblical texts, to indicate how the text should be voiced when sung/chanted and these should also remain clear.
