Cursor 2.6.20+版本Python终端处理含Unicode框画字符的Python注释时崩溃的解决方案咨询

我平时用Cursor写Python脚本调试时，习惯选中代码块通过Shift+Enter或者复制粘贴的方式，发送到内置的Python终端执行——这个操作之前一直很顺畅，但自从更新到Cursor 2.6.20版本后就出问题了。其实更早几个版本就存在这个bug，之前我是靠回滚版本来规避的，但这次想找个根本解决办法。

问题场景与代码示例

我的代码里会保留Polars DataFrame结构的注释，用来方便调试时参考，代码类似这样：

print('a')
# ┌──────────┬──────┬────────┬─────────────────┬────────────────────┬────────┐
# │ aaaaaaaa ┆ bbb  ┆ cccccc ┆ ddddddddddddddd ┆ eeeeeeeeeeeee      ┆ ffffff │
# │ ---      ┆ ---  ┆ ---    ┆ ---             ┆ ---                ┆ ---    │
# │ i32      ┆ i32  ┆ i32    ┆ u32             ┆ list[i32]          ┆ i64    │
# ╞══════════╪══════╪════════╪═════════════════╪════════════════════╪════════╡
# │ 4        ┆ 5911 ┆ 0      ┆ 61373           ┆ [0, 1, … 95944]    ┆ 0      │
# │ 7        ┆ 5911 ┆ 0      ┆ 61373           ┆ [0, 1, … 95944]    ┆ 1      │
# │ 7        ┆ 5711 ┆ 0      ┆ 58129           ┆ [0, 2, … 95943]    ┆ 2      │
print('b')

症状表现

当我把这段包含Unicode框画字符注释的代码发送到Cursor内置Python终端时，终端会直接挂掉崩溃；但完全相同的操作在Mac自带的原生终端里执行，没有任何问题。

更新到Python 3.14.3后，还弹出了具体的错误栈：
