QChar: plaster API with Q_DECL_NOTHROW
This is mostly straight-forward, but some things are worth noting: 1. Yes, this is necessary. The noexcept operator looks for noexcept tagging, not at the contents of the function to determine whether to return true. The more conditionally-noexcept functions are used, the more important it becomes that low-level classes are correctly marked noexcept. In that, it is like constexpr. 2. The decomposition() functions, returning a QString, can throw (bad_alloc). Consequently, they're not marked nothrow. they're the only ones.
