mConfig

final WriterConfig mConfig

mAutoCloseOutput

final boolean mAutoCloseOutput

mOut

OutputStream mOut

mOutBuffer

byte[] mOutBuffer

mOutBufferLast

final int mOutBufferLast

mOutPtr

int mOutPtr

mSurrogate

int mSurrogate

When outputting chars from BMP, surrogate pairs need to be coalesced. To do this, both pairs must be known first; and since it is possible pairs may be split, we need temporary storage for the first half
