N2 - The variable-length source coding with unequal cost allowing error probability is considered for general sources. In this setting, the first- and second-order optimum mean codeword cost have already been determined. On the other hand, we focus on the overflow probability of codeword cost and determine the general formulas of the first- and second-order optimum achievable overflow threshold. We also apply our general formulas to the stationary memoryless source.
