Bug report

Bug description:

In 3.14, the t-string is supported, but the IDLE still hardcodes the string prefix pattern (r, u, b, f, rb, br, fr, rf),
but does not delegate to the standard tokenize module.

The question of the hardcodes cannot fix quickly. However, change the code in make_pat here can fix the question above:

stringprefix = r"(?i:r|u|f|t|fr|rf|b|br|rb|rt|tr)?"

If there are more supported combinations we can add them.
