minibuffer-allow-text-properties

minibuffer-allow-text-properties is a variable defined in `C source code'.
Its value is

nil

Documentation:
Non-nil means `read-from-minibuffer' should not discard text properties.
This also affects `read-string', but it does not affect `read-minibuffer',
`read-no-blanks-input', or any of the functions that do minibuffer input
with completion; they always discard text properties.
