/*
* To detect legacy cache-lookup call from a rogue client (<= 2.1.7),
* we restrict the number of charmaps in a font. The current API of
* FTC_CMapCache_Lookup() takes cmap_index & charcode, but old API
* takes charcode only. To determine the passed value is for cmap_index
* or charcode, the possible cmap_index is restricted not to exceed
* the minimum possible charcode by a rogue client. It is also very
* unlikely that a rogue client is interested in Unicode values 0 to 15.
*
* NOTE: The original threshold was 4 deduced from popular number of
* cmap subtables in UCS-4 TrueType fonts, but now it is not
* irregular for OpenType fonts to have more than 4 subtables,
* because variation selector subtables are available for Apple
* and Microsoft platforms.
