commit 30c303 "Make charmap.cxx compile with icu >= 4.4." was incomplete
and had wrong version checks. After ICU 4.8 (4.8.1.1) the next version
of ICU was 49 (49.1) so U_ICU_VERSION_MAJOR_NUM contains two digets (49),
earlier that it was just one digit (4). The correct header to include to
do version checks is unicode/uversion.h. USCRIPT_MANDAEAN is the old
alias of USCRIPT_MANDAIC (same numeric value). U_JG_FARSI_YEH is only
available since ICU 4.4. Note that on older icu versions (4.2.1) the
200B (ZWSP) Zero Width Space breakiterator testcase fails (others
succeed).
