I'm using the following code in my forked project [1]:

percol.view.STACKLINE = 'Fold:F1,F2,F3 Push:C-p Pop:M-p Script:M-s Dir:M-d Dircmd:M-b'

I would like to change the display style of the text mentioned above, for example, to underline some characters in it, as shown below:

_D_ir:M-d

How to achieve this purpose?

You can use e.g. str.replace() or re.sub()

>>> percol.view.STACKLINE = percol.view.STACKLINE.replace('D', '_D_')
Result: 'Fold:F1,F2,F3 Push:C-p Pop:M-p Script:M-s _D_ir:M-d _D_ircmd:M-b'

>>> import re

Replace D with _D_
>>> percol.view.STACKLINE = re.sub(r'([D])',
r'_\1_', percol.view.STACKLINE)
Result: 'Fold:F1,F2,F3 Push:C-p Pop:M-p Script:M-s _D_ir:M-d _D_ircmd:M-b'

Replace D and M with _D_, _M_
>>> percol.view.STACKLINE = re.sub(r'([DM])', r'_\1_',
percol.view.STACKLINE)
'Fold:F1,F2,F3 Push:C-p Pop:_M_-p Script:_M_-s _D_ir:_M_-d _D_ircmd:_M_-b'

I tried with the following, but failed to achieve the expected effect:

class Term:
HEADER = '\033[95m'
OKBLUE = '\033[94m'
OKGREEN = '\033[92m'
WARNING = '\033[93m'
FAIL = '\033[91m'
ENDC = '\033[0m'
LIGHTCYAN = '\033[1;36m'
LIGHTGRAY = '\033[0;37m'
YELLOW = '\033[0;33m'
BOLD = '\033[1m'
UNDERLINE = '\033[4m'

[...]

percol.view.STACKLINE = percol.view.STACKLINE.replace('D', Term.UNDERLINE + 'D' + Term.ENDC)

The result will look like this:

Fold:F1,F2,F3 Push:C-p Pop:M-p Script:M-s ?[4mD?[0mir:M-d ?[4mD?[0mircmd:M-b

Python 3.9.6 (default, Jul 16 2021, 00:00:00)
[GCC 11.1.1 20210531 (Red Hat 11.1.1-3)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> UL = '\033[4m'
>>> UL
'\x1b[4m'
>>> ENDC = '\033[0m'
>>> ENDC
'\x1b[0m'

>>> s = UL + 'D' + ENDC
>>> s
'\x1b[4mD\x1b[0m'

>>> s = 'ABCDE'
>>> s = s.replace('D', UL + 'D' + ENDC)
>>> s
'ABC\x1b[4mD\x1b[0mE'

When I call print(s) it even shows ABCD and D is underscored. But copying
the output to mail looses the underscore ...

If the terminal understands unicode, Combining Low Line: U+0332
might help

If I test the code snippet above with ipython/ptpython/python, I got the same result as you described. But the problem I reported here is triggered by running the command line wrapper of the project by `Ctrl-r`, which is worked with curses library. And I also noticed the following file [1] used by the project, which may be pertinent to the problem discussed here.
But till now I still can't think of a solution.
