01.000.002 - code.txt: en and em dashes read as hyphens

Autocorrect (Word, Edge, Windows) can turn the hyphens in a typed product code into an en dash (–) or an em dash (—). The registry can't take those, so the install stopped. code.txt now reads both as a plain hyphen. Also includes 01.000.001: UTF-16 code.txt, non-breaking and zero-width spaces trimmed, and a clearer message that names the file.
