[BUG] Roo things ' and ' are the same and fails to apply the change

[Lissanro]

Problem (one or two sentences)

I keep getting error like this:

src/components/docs/FAQ.jsx - Diff 1: Search and replace content are identical - no changes would be made

Debug Info:
- Search and replace must be different to make changes
- Use read_file to verify the content you want to change

The model correctly tries to replace ' with ':

From:

token   1379: ' This'
token   8370: ' doesn't'
token   3594: ' change'

To:

token   1379: ' This'
token   8248: ' doesn'
token  15032: '&apos'
token  40876: ';t'
token   3594: ' change'

And yet Roo Code claims they are the same and errors out. The content of the file does not get corrected, so the model keep getting the same eslint error and trying it over and over, and Roo Code keeps mistakenly identifying completely different token sequences as "the same". This suggests comparison happens on processed strings where escaped characters are converted to the their final form, which should not be happening - it is important that exact raw string are used for search and replace.

Context (who is affected and when)

I think everyone is affected who often edits .jsx files and uses eslint checks. There is possibility Roo Code may have broken comparison for other similar escaped characters, not just apostrophe. So far, I ended up replacing it manually but since this bug isn't fixed for a while and I did not find other reports about it, I decided to create one myself.

Reproduction steps

Ask the model to correct syntax error like this in a .jsx file:

This doesn't change

(it should be This doesn't change)

The specific error:

`'` can be escaped with `'`, `‘`, `'`, `’`.eslint[react/no-unescaped-entities](https://github.com/jsx-eslint/eslint-plugin-react/tree/master/docs/rules/no-unescaped-entities.md)

I am using Kimi K2 0905 with XML tool calls (Roo Code default).

Expected result

Replace ' with '

Actual result

Replace ' with ' does not happen and Roo Code stops the model after few tries, even though it produced correct search-replace pattern successful every time

I'm exploring a potential fix for this issue where HTML entities are incorrectly identified as identical to their decoded characters during diff operations. This appears to be affecting JSX files when trying to escape characters like apostrophes. I'll investigate the comparison logic in the apply_diff tool and open a PR to share progress.

[roomote]

Opened a PR with my attempt at addressing this issue. Feedback welcome!

The root cause was the unescapeHtmlEntities function being applied to diff content for non-Claude models, which converted HTML entities before comparison. This has been fixed by removing that conversion.

PR: #9564

[Lissanro]

@roomote Unfortunately, it still replaces ' (and likely all other HTML entities) with their corresponding character equivalents. For example, even if I ask to use sed or perl to replace apostrophe with ', then model generated correct tokens:

token	  9413: 'Let'
token	  1019: ' me'
token	  1328: ' use'
token	   276: ' the'
token	 14793: ' execute'
token	 20975: '_command'
token	  4453: ' tool'
token	   472: ' with'
token	 78120: ' perl'

token	   993: '</'

token	 20975: '_command'
token	    29: '>'

But in Roo Code I see:

perl -p -i -e "s/you're/you're/g" src/components/AuctionCreations.jsx

I also noticed that at first it was ', but just for a brief moment, then it suddenly is replaced with the actual apostrophe symbol. If I run this command, file content remains exactly the same, suggesting that it was indeed replaced.

Roo Code should never replace HTML entities with their corresponding characters in neither apply_diff nor any other tool call, this just breaks things, making it impossible to work with any .tsx or .jsx files where I need to have actual HTML entities.

[roomote]

I've seen your comment and will investigate this further. It appears that while PR #9564 addressed the HTML entity issue for apply_diff, the problem persists for execute_command and potentially other tool calls. The user reports that HTML entities like \) in the displayed command.

I'll explore the codebase to find where this conversion is happening and work on a fix. Will open a PR to share progress.
