## Bengali character table ##

Bengali glyphs should be classified as in the following
table. Codepoints in the Bengali block with no assigned meaning are
designated as _unassigned_ in the _Unicode category_ column. 

Assigned codepoints with a _null_ in the _Shaping class_
column evoke no special behavior from the shaping engine. Note that
this does include some valid codepoints, such as currency marks,
punctuation, and other symbols.

> Note: the `NUMBER` and `SYMBOL` _Shaping classes_ are important
> during syllable identification, but generally evoke no further
> special behavior during the rest of the shaping process. 

The _Mark-placement subclass_ column indicates mark-placement
positioning for codepoints in the _Mark_ category. Assigned, non-mark
codepoints have a _null_ in this column and evoke no special
mark-placement behavior. Marks tagged with [Mn] in the _Unicode
category_ column are categorized as non-spacing; marks tagged with
[Mc] are categorized as spacing-combining.

Some codepoints in the following table use a _Shaping class_ that
differs from the codepoint's Unicode _General Category_. The _Shaping
class_ takes precedence during OpenType shaping, as it captures more
specific, script-aware behavior.

## Miscellaneous character table ##

In addition to general punctuation, runs of Bengali text often use the
danda (`U+0964`) and double danda (`U+0965`) punctuation marks from
the Devanagari block. Bengali text can also incorporate the udatta
(`U+0951`) and anudatta (`U+0952`) signs from the Devanagari block.

Other important characters that may be encountered when shaping runs
of Bengali text include the dotted-circle placeholder (`U+25CC`), the
zero-width joiner (`U+200D`) and zero-width non-joiner (`U+200C`), and
the no-break space (`U+00A0`).

The dotted-circle placeholder is frequently used when displaying a
dependent vowel (matra) or a combining mark in isolation. Real-world
text syllables may also use other characters, such as hyphens or dashes,
in a similar placeholder fashion; shaping engines should cope with
this situation gracefully.

:::

The zero-width joiner (<abbr>ZWJ</abbr>) is primarily used to prevent the formation
of a conjunct from a "_Consonant_,Halant,_Consonant_" sequence. The
sequence "_Consonant_,Halant,ZWJ,_Consonant_" blocks the formation of
a conjunct between the two consonants. 

Note, however, that the "_Consonant_,Halant" subsequence in the above
example may still trigger a half-forms feature. To prevent the
application of the half-forms feature in addition to preventing the
conjunct, the zero-width non-joiner (<abbr>ZWNJ</abbr>) must be used instead. The
sequence "_Consonant_,Halant,ZWNJ,_Consonant_" should produce the
first consonant in its standard form, followed by an explicit
"Halant".

A secondary usage of the zero-width joiner is to prevent the formation of
"Reph". An initial "Ra,Halant,ZWJ" sequence should not produce a "Reph",
where an initial "Ra,Halant" sequence without the zero-width joiner
otherwise would.

The no-break space (<abbr>NBSP</abbr>) is primarily used to display those
codepoints that are defined as non-spacing (marks, dependent vowels
(matras), below-base consonant forms, and post-base consonant forms)
in an isolated context, as an alternative to displaying them
superimposed on the dotted-circle placeholder. These sequences will
match "NBSP,ZWJ,Halant,_Consonant_", "NBSP,_mark_", or "NBSP,_matra_".
