The magic search works case-sensitive if you use a language other than English.

Hi, thanks for your cool app.

1. Describe the bug

The magic search works case-sensitive if you use a language other than English.

If I start searching for a contact signed in Ukrainian, the search works only in case-sensitive English, everything works fine, case-insensitive.

2. To Reproduce

Create outlines with a capital letter
Андрій
Олександр
Марія

Try to add one of the contacts to the group by writing the name with a little boova
андрій
's contact Андрій will not be found

3. Expected behavior

It is expected that the contact search will work the same way as in English, case-insensitive.

I tried to fix the problem, but my knowledge wasn't good enough.

Here's what I found:

1. The search is performed using regular expressions. The setupRegex function in magic-search.cpp
   creates a regular expression from the search string.
2. The lines are reduced to lowercase. The setupRegex and getWeight functions have both a filter and a text.,
   which is being searched for, converted to lowercase using tolower(). It means,
   that the search should already be case insensitive.

However, there is one caveat. setupRegex uses std::regex, and getWeight uses
regex_match. By default, std::regex can be case-sensitive depending on
the compiler and OS implementation.

To ensure case insensitivity, I will add the std::regex::icase flag when
creating the std::regex object.

4. Please complete the following information

• Device: RedmiNote 12
• OS: Android 13
• Version of the App 6.0.19
• Version of the SDK 5.5.0-alpha.31210+3af4d45ca2
• Where you did got it from use Play Store and build from https://github.com/BelledonneCommunications/linphone-android/
  Android MIUI Global 14.0.8.

5. SDK logs

Does not write any errors in the logs

6. Adb logcat logs

Thank you.

Hi @Randry1,

Yes we are aware of that and we plan on addressing it someday.

Cheers,
