Unicode blocks in pattern not recognized

[manoe]

libyang supports patterns that further restrict a string leaf's set of values. The YANG RFC [1] allows the use of Unicode blocks [2] in patterns (e.g. Basic Latin, Cyrillic). libyang, due to a coding error, interprets every Unicode block pattern as Latin-1 Supplement, if multiple Unicode blocks are present in the same pattern. In the corresponding code, the variable responsible to store the Unicode block information, gets overwritten.
