960007e58e Fix compiler warning (possible loss of data) (#1370)
Fix 306 warnings from MS C:

tesseract\ccutil\unicharset.h(242): warning C4267:
 'argument': conversion from 'size_t' to 'int', possible loss of data

The change also avoids some type conversions.

da03e4e910 Fixes from pull of cleanups: clang tidied, reviewed, fixed new bugs, undeleted needed code. Probably breaks the build, due to some inclusion of changes in utf8/32 conversion 2017-07-14 09:30:14 -07:00

69296f8d18 Clean method UNICHARSET::add_script
It increased the script_table too early, so the last element was never
used.
