-- 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 //etc. that --     don't include an explicit hyphen).

-- Per-script template hyphens. The template hyphen is what appears in the -- ///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 / -- /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.
