I've been hunting though the Unicode ranges for the correct codepoints for these. Haven't found any yet. Anyone have any info? 
MIcrophone off/ Microphone on/ Search/ Speaker off/ Speaker on 
Thanks in advance

    Speaker symbols are U+1F507-1F05A. Magnifying glass is U+1F50D. There's not really a microphone off/on codepoint, but there is a microphone at U+1F3A4.

    Could combine the microphone with the “combining enclosing circle backslash” character, U+20E0, for the microphone-off

    Not perfect, but I don’t think it is illegitimate either.

    Thanks Thomas.
    How would you write this: 1F34A+20E0?

    Typo: should be 1F3A4

    You could set up a ccmp feature ligation for /u    1F3A4_uni20E0 but note that this may not work because U+1F3A4 is an emoji character so software may fall back to the system emoji font instead of using yours, meaning that the substitution doesn’t happen.

    Thank you for your advice John. This font is for a sealed environment with no interaction with any computer or additional fonts (flight deck implementation). The client has previously mapped these glyphs to particular ascii slots. I was thinking that mapping them to proper unicode would be an improvement, but in the end I think not

    If it is a closed environment, then using PUA codepoints is probably workable.
