This reverts commit 116b589.
E2BIG shall be returned if the output buffer is too small. We pass a 64 byte buffer which should be enough to do *something* However it is observed on MacOS Sonoma that iconv returns E2BIG without doing any progress leading to an infinite loop as the same inputs will be passed over and over. See boostorg#206. Instead raise an exception when this case is detected.
