yyrestart: fix first FILE* character getting swallwed #179

Closed jmaebe closed 1 year ago

jmaebe commented 1 year ago

The Input constructor was being called twice, thereby twice reading the "first" character to check for an UTF signature and only caching the second one for use during parsing.

resolves #178

Thanks for your patience. This looks important. I had no time to work on this unit now and will catch up this weekend.
