`more` doesn't properly support upper-range BMP / 3B UTF-8 chars

Environment

Win32NT             10.0.19042.0 Microsoft Windows NT 10.0.19042.0
Windows Terminal version: latest Preview from store

Any other software?
TSDuck (console application)

Steps to reproduce

1. download latest tsduck nightly from https://tsduck.io/download/prerelease/
2. download eit.zip from https://github.com/tsduck/tsduck/issues/720 (at the top of report) and extract eit.ts
3. extract tsduck and run bin\tstables.exe --japan eit.ts
4. The output looks like this:

Expected behavior

After repeating 1-3 above, the output should look like the third image here https://github.com/tsduck/tsduck/issues/720#issuecomment-770239722 (2 lines of Japanese text, "Event name:" and "Description:" followed by Japanese text.

      Event name: "日本共産党自主放送"
      Description: "色は匂へど散りぬるを我が世誰ぞ常ならん有為の奥山今日越えて浅き夢見じ酔ひもせず"

Actual behavior

Entire "Description: " line is NOT displayed, like it simply doesn't exist.
Note, the same problem occurs in cmd.exe and powershell command prompts (using native win32 console), so I'm not actually sure what causes the problem, but according to tsduck dev it is windows/terminal/console fault.

Additionally, if using console redirection, such as bin\tstables.exe --japan eit.ts > file.txt from cmd.exe, both Japanese lines are present in file. So they're definitely being "printed" just not displayed.

Reproduce with TSDuck's bin\tstables.exe --japan eit.ts using the eit.ts file from tsduck/tsduck#720, then compare Windows Terminal, cmd.exe, and PowerShell with redirected output. Trace the console display path for the missing Japanese Description line; done means both Japanese lines render while redirection continues to include them.
