Use skip_ascii() in no_conversion_convert() when encoding. src/ChangeLog addition: 2013-12-19 Aidan Kehoe <kehoea@parhasard.net> * text.c: * text.h: * text.h (skip_ascii): Move skip_ascii (), the very fast inline function from the bytecount-to-charcount code, to text.h, to allow the coding systems to use it too as needed. * file-coding.c (no_conversion_convert): Use skip_ascii() as appropriate here, halving the time taken to write large files in my tests (again, relevant to VM buffers, but not a panacea to our issues with them.)
