receiving, from the source client device associated with the communication system, a second input string; and

in response to a second determination that the second input string is associated with a universal format of the one or more universal formats, transmitting the second input string to the one or more destination client devices without performing a second format modification to the second input string.

9. A communication system comprising:

one or more processors; and

one or more non-transitory computer-readable media storing instructions that, when executed by the one or more processors, cause the communication system to perform operations comprising:

identifying one or more universal formats associated with the communication system;

identifying one or more non-universal formats associated with the communication system, wherein a non-universal format of the one or more non-universal formats includes a format that does not satisfy a usage condition associated with a threshold number of users of the communication system, and wherein the usage condition comprises the format being used at least once by the threshold number of users;

receiving, from a source client device associated with the communication system, an input string;

in response to a determination that the input string is associated with the non-universal format, performing a format modification to the input string; and

transmitting a modified input string to one or more destination client devices.

10. The communication system of claim 9 , wherein identifying the one or more universal formats and the one or more non-universal formats comprises, for a supported structured format associated with the communication system:

determining a condition associated with the supported structured format;

in response to a second determination that the condition satisfies one or more first thresholds, determining that the supported structured format is one of the one or more universal formats; and

in response to a third determination that the condition fails to satisfy one or more second thresholds, determining that the supported structured format is one of the one or more non-universal formats.

11. The communication system of claim 10 , wherein the condition comprises at least one of:

a first number of users, of the communication system, that have installed the supported structured format;

a second number of users, of the communication system, that have used the supported structure format at least once; or

a third number of users, of the communication system, that have used the supported structure format on a frequent basis.

12. The communication system of claim 9 , wherein performing the format modification to the input string comprises generating one or more fallback data objects for the input string, wherein an individual fallback data object of the one or more fallback data objects includes content data associated with the input string formatted in accordance with a universal format of the one or more universal formats.

13. The communication system of claim 12 , wherein transmitting the modified input string to the one or more destination client devices comprises transmitting the input string and at least one fallback data object of the one or more fallback data objects to the one or more destination client devices.

14. The communication system of claim 9 , the operations further comprising:

receiving, from the source client device associated with the communication system, a second input string; and

in response to a second determination that the second input string is associated with a universal format of the one or more universal formats, transmitting the second input string to the one or more destination client devices without performing a second format modification to the second input string.

15. One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause a communication system to perform operations comprising:

identifying one or more universal formats associated with the communication system;

identifying one or more non-universal formats associated with the communication system, wherein, a non-universal format of the one or more non-universal formats includes a format that does not satisfy a usage condition associated with a threshold number of users of the communication system, and wherein the usage condition comprises the format being used at least once by the threshold number of users;
