35a999f91a Fix assertion caused by wrong unicharset 
Credit to OSS-Fuzz: it found another case which triggered this assertion:

    contains_unichar_id(unichar_id):Error:Assert failed:in file ../../src/ccutil/unicharset.h, line 502

This is the OSS-Fuzz testcase:

56a39bda77 Fix float division by zero 
That runtime error is normally not visible because it does not abort
the program, but is detected when the code was compiled with sanitizers.

It can be triggered with this OSS-Fuzz testcase:

4c0b98bd12 Replace undefined shift operations by multiplications 
Shift operations are undefined for negative numbers, but at least on
Intel they return the same value as a multiplication with 2 ^ shift value.

This fixes runtime errors reported by sanitizers and OSS-Fuzz:

    intmatcher.cpp:821:59: runtime error: left shift of negative value -14
    intmatcher.cpp:823:75: runtime error: left shift of negative value -512
    intmatcher.cpp:820:50: runtime error: left shift of negative value -80

See issue #2297 and
