Display Issues

Text with special (extended) characters does not render properly

Reason:

This is a known limitation of MediaPortal's font engine. When rendering text, especially when rotating or scrolling, if a character in the string is outside the range of characters rendered to textures, the font engine will use an alternate method to render the text. It will use DirectX sprites. Sprites are 2D objects and cannot extend on the z-axis. When rendering sprites, only the part that lies on the z=0 plane is visible - everything else is clipped.

An error.log will be created which should have entries similar to this:

If you open the TV Guide on client side you will get a picture similar to this:

 

Resolution:

  1. Navigate to the folder: 

    Code Block
    languagephpxml
    C:\ProgramData\TeamMediaPortal\MediaPortal TV Server

    (note:

    Code Block
    languagephpxml
    ProgramData

    is a hidden folder)

  2. Open

    Code Block
    languagephpxml
    gentle.config

    with a text editor

  3. Search for the line which looks similar to:
Code Block
languagebrush: plain; collapse: false; first-line: 1; gutter: true; ruler: false; toolbar: true; wrap-lines: true;text
<DefaultProvider name="MySQL" connectionString="Server=localhost;Database=MpTvDb;User ID=root;Password=MediaPortal;charset=utf8;Connection Timeout=300;" />
  1. Change the red marked word above to:
Code Block
languagebrush: plain; collapse: false; first-line: 1; gutter: true; ruler: false; toolbar: true; wrap-lines: true;text
<DefaultProvider name="MySQL" connectionString="Server=<NameOfMyTVServer>;Database=MpTvDb;User ID=root;Password=MediaPortal;charset=utf8;Connection Timeout=300;" />

...

If this does not help and you still don't get a database connection look for the

Code Block
languagephpxml
gentle.config

in 

Code Block
languagephpxml
C:\ProgramData\Team MediaPortal\MediaPortal
