Hi, This thread is a bit confusing to me, so if there is an actual question to me, someone has to rephrase it (and keep in mind that I have not used gnuplot in 'ages'). Mojca Miklavec wrote:

Should this not be set ylabel "h\\dochar {233}llo" because of GNUplot's own double-quoted string parsing? Independent of expansion in \startGNUPLOTscript, I mean? Speaking as the maintainer of Metapost, assuming 'plain.mp': you should be able to use UTF-8 in btex ... etex under the following (narrow) conditions: * you have set up the verbatimtex .. etex properly so that your macro package nows how to handle the UTF-8 input; * your tex engine generates DVI files * the resulting fonts that are used in that DVI are TFM-based. For context, that would mean mkii pdftex with \enableregime[utf], but in that case, you are much better off using \textext. You cannot have UTF-8 in literal metapost label strings, because Metapost only knows about traditional TFM fonts (single byte). Best wishes, Taco
