Resolve Cocos Creator font-atlas capacity warnings by adjusting cache mode, font size, atlas size, or character set.

The browser displayed:

1 2	The font size is too big to be fitted into texture atlas. Please switch to other label cache modes or choose a smaller font size.

In Bitmap cache mode, the usable font size depends on atlas dimensions, number and complexity of characters, and other atlas content. There is no universal maximum.

Try these measures:

Test smaller sizes first; 20–40 is often a practical starting range.
Verify that the texture atlas is large enough. A common maximum is 2048×2048, depending on project and device settings.
Reduce the character set if the label uses only a limited range.
Select the Label node, set Cache Mode to BITMAP, and increase the font size gradually until the warning appears.
If necessary, use another cache mode rather than forcing the text into one atlas.

The problem may appear only under extreme text combinations; a font size that normally works can still overflow later.
