[nongnu] elpa/flycheck ddca9f7729 01/11: Isolate bidi characters in error message snippets

[ELPA Syncer]

branch: elpa/flycheck
commit ddca9f77297adbebf673f845b8d4a473b5d75df2
Author: Bozhidar Batsov <bozhi...@batsov.dev>
Commit: Bozhidar Batsov <bozhi...@batsov.dev>

    Isolate bidi characters in error message snippets
    
    Wrap error snippets in Unicode directional isolate characters
    (U+2068 FIRST STRONG ISOLATE / U+2069 POP DIRECTIONAL ISOLATE)
    to prevent bidirectional formatting characters in source code from
    corrupting error message display.
    
    Fixes #1919
