As shown in the picture, the first picture is in English language, the second picture is in Chinese language.
For the same search history, the search results in English language *.* without (A), while the Chinese language with (A). I've tested this with other languages, and the same thing happens with Japanese and Korean, which extends the problem that the shortcut key characters are typed into the search field along with the search history when the search results are brought up to the screen. For example, if I click on *.*(A), the characters in the lookup field will be *.*(A) instead of *.*.
Many thanks. The (A) and (B) are there to provide accelerators (only happens in languages like Chinese and Japanese where it's normal for other parts of the UI to add them like that), but it's a bug that they are being inserted back into the search field when you select them.
We've fixed that for the next beta, so the (A), (B) etc. are not inserted into the field.
(By the way, you should use * if you want to find everything below a folder. *.* will only find things with a dot in their names. Opus doesn't use the old MS-DOS wildcard conventions where a blank extension is assumed to be on the end of all file and folder names and *.* matches everything.)
