Do 'a' and '0' always have positive values even if char is signed?

由 北慕城南 提交于 2020-01-11 04:33:06
问题 Depending on the environment and compiler settings, the type char can be signed or unsigned by default, which means the range of values for single character constants on 8-bit 2s complement systems can be either -128..127 or 0..255 . In the ubiquitous ASCII character set, its ISO-8859-X extensions or the UTF-8 encoding, upper- and lowercase letters as well as digits have values below 127. But such is not the case with the EBCDIC character set: 'A' is 0xC1, 'a' is 0x81 and '1' is 0xF1. Since

Oracle 11g XE greek character set not displaying

由 孤人 提交于 2020-01-09 05:40:18
