The adoption of P2675 (LWG3780: The Paper: format's width estimation is
too approximate and not forward compatible) <https://wg21.link/p2675>
prompted me to file an enhancement request for ICU to consider providing
an interface to query EGC display width for monospace applications.

  * ICU-22344 <https://unicode-org.atlassian.net/browse/ICU-22344>:
    Support for estimating the monospace display width of a sequence of
    EGCs in a terminal or console

Please feel free to take a look and offer corrections or additional
comments.

Tom.
