I shan't mention one of my former employers then who advised users to avoid the GBP STG symbol because it caused issues with their ANSI (!!!) password read/write mechanisms.

Indeed. The context I've seen it was early version of MIT Kerberos encoding the password to iso-8859-1 versus Windows 2000 which encodes to UTF8. In that situation, any character not in the basic US-ASCII range
32-126 inclusive was unsafe to use cross-platform.

We still advise people to avoid non-ASCII characters in passwords :o(
