Re: How to represent the letter phi

No you don't. UTF-8 was specifically engineered to map to the same
code points as ASCII for values from 0 to 159, and to be able to
reach code points up to U+FFFF (at least, may also be the full 32-bit
range) with its use of the values from 160 to 255.

The OP should understand the difference between Unicode and character sets with codepages. Transferring a character "phi" over a serial line can be done in many ways, with the most simple case that the sender and receiver agree about using a specific code page, where that character has an unique 8-bit code.

When a concrete receiver program is given, the transmission must follow the implemented protocol and interpretation of the data bytes. When the receiver has to be implemented, an appropriate protocol can be choosen and implemented, that may be based on codepages or on Unicode, depending on the overall task.
