dndbeyond: Unicode characters on monster pages

[dmportella]

Describe the bug
When rolling a monster ability check, saving throw, or skill check that has a negative modifier (e.g., Strength −2), the result is calculated as if the modifier was positive. The roll result shows a value that is too high by double the modifier amount.

To Reproduce
Steps to reproduce the behavior:

1. Go to a monster page on D&D Beyond that has negative ability/save modifiers (e.g., Wraith, Shadow, or any monster with a negative stat)
2. Click on the roll button for an ability with a negative modifier (e.g., Strength which shows "−2")
3. Check the roll result sent to the VTT or shown in the roll dialog
4. The result is calculated as 1d20 + 2 instead of 1d20 − 2

Expected behavior
Rolling a monster ability/save/skill with a negative modifier should correctly subtract that value from the d20 roll. For a Wraith's Strength (−2), rolling should produce results in the range of −1 to 18 (1d20−2), not 3 to 22 (1d20+2).

Screenshots
To help explain your problem, add screenshots of:

• The monster stat block showing the negative modifier (e.g., STR −2)
• The Beyond20 roll result showing an incorrectly high total
• The sent request JSON showing "roll": "1d20−2" with Unicode minus

Browser Info (please complete the following information):

• Browser: Chrome/Firefox/Edge (any)
• Version: any
• If applicable, any dev console errors: None - the roll appears to succeed but with incorrect math

Additional context

• The issue affects all monster rolls: ability checks, saving throws, skill checks, and initiative
• The root cause is that D&D Beyond uses Unicode minus sign (U+2212, −) for negative modifiers, but the extension's formula parser only recognizes ASCII hyphen-minus (U+002D, -)
• Example: Wraith monster page - https://www.dndbeyond.com/monsters/wraith (STR −2, Save STR −2)

Is this a new issue or a regression caused by DDB changes?
