/*
* APL keysym translation.
*
* This code looks a little odd because of how an APL font is implemented.
* An APL font has APL graphics in place of the various accented letters and
* special symbols in a regular font. APL keysym translation consists of
* taking the keysym name for an APL symbol (these names are meaningful only to
* x3270) and translating it into the keysym for the regular symbol that the
* desired APL symbol _replaces_.
*
* For example, an APL font has the APL "jot" symbol where a regular font has
* the "registered" symbol. So we take the keysym name "jot" and translate it
* into the keysym XK_registered. When the XK_registered symbol is displayed
* with an APL font, it appears as a "jot".
*
* The specification of which APL symbols replace which regular symbols is in
* IBM GA27-3831, 3174 Establishment Controller Character Set Reference.
*
* In addition, several standard characters have different names for APL,
* for example, "period" becomes "dot". These are included in the table as
* well.
