Not displaying symbols correctly

The underlying reasons for getting the wrong 'glyph' (character shape) is that the sender and the receiver are not using (or do not support) the same coded character set.
Within the 8-bit ISO8859/1 coded character set (which matches row 0 of the BMP within Unicode), two of the characters you mention are assigned the codes:
0xa9 (decimal 169; Unicode U+00A9) Copyright symbol
0xae (decimal 174; Unicode U+00AE) Registration Mark symbol
The standard Windows ANSI coded character set is a superset of ISO 8859/1; the difference is that it makes use of codes, in the range 0x80-0x9f, which in ISO8859/1 are considered to be 'undefined control codes'.
One of these code positions provides the other symbol:
0x99 (decimal 153; Unicode U+2022) Trade Mark symbol
provided that (both ends) assume use of the Windows ANSI coded character set.
HP LaserJet PCL5 devices refer to coded-character sets via 'Symbol Set' identifiers; the identifier associated with 'Windows ANSI' is 19U.
