The original bug was found when developing Juila parser in u-ctags
repo[1]. When searching a tag name "α", readtags reported nothing
though an entry for "α" was in the tags file used for testing
the Julia parser.
"α" is {206, 177} as a byte sequence.
However, when comparing bytes in strings, libreadtags used (singed)
char type. In the case "α" was {-50, -79}. Using {-50, -79} for
comparison, the binary search didn't work as we expected.
The test for this change will be done in u-ctag side.
