tc­com­pat – Pro­vide com­pat­i­bil­ity names for textcomp.sty

When TS1 (text sym­bol) sup­port was in­te­grated into the LaTeX ker­nel, some of the en­cod­ing-de­pen­dent names used in older ver­sions of the textcomp pack­age were changed. This pack­age re-de­clares those names for com­pat­i­bil­ity use in old doc­u­ments.
