-- ABOUT TEMPLATE AND DISPLAY HYPHENS:
--
-- The "template hyphen" is the per-script hyphen character that is used in
-- template calls to indicate that a term is an affix. This is always a single
-- Unicode char, but there may be multiple possible hyphens for a given script.
-- Normally this is just the regular hyphen character "-", but for some
-- non-Latin-script languages (currently only right-to-left languages), it
-- is different.
--
-- The "display hyphen" is the string (which might be an empty string) that
-- is added onto a term as displayed (and linked), to indicate that a term
-- is an affix. Currently this is always either the same as the template
-- hyphen or an empty string, but the code below is written generally enough
-- to handle arbitrary display hyphens. Specifically:
--
-- (1) For East Asian languages, the display hyphen is always blank.
-- (2) For Arabic-script languages, either tatweel (ـ) or ZWNJ (zero-width
--     non-joiner) are allowed as template hyphens, where ZWNJ is supported
--     primarily for Farsi, because some suffixes have non-joining behavior.
--     The display hyphen corresponding to tatweel is also tatweel, but the
--     display hyphen corresponding to ZWNJ is blank (tatweel is also the
--     default display hyphen, for calls to {{prefix}}/{{suffix}}/etc. that
--     don't include an explicit hyphen).

-- List of all Arabic scripts.
local arab_scripts = {
	"Arab",
	-- WTF? Why are there a zillion language-specific variants of the
	-- Arabic script?

-- Per-script template hyphens. The template hyphen is what appears in the
-- {{affix}}/{{prefix}}/{{suffix}}/etc. template (in the wikicode). See below.
--
-- The value below is a string consisting of one or more hyphen characters.
-- If there is more than one character, a non-default function must be
-- specified for the script in display_hyphens[] so the correct display
-- hyphen will be specified when no template hyphen is given (in {{suffix}}/
-- {{prefix}}/etc.).
--
-- Script detection is normally done when linking, but we need to do it
-- earlier. However, under most circumstances we don't need to do script
-- detection. Specifically, we only need to do script detection for a given
-- language if
--
-- (a) the language has multiple scripts; and
-- (b) at least one of those scripts is listed below or in display_hyphens.
