Cause
The jumbled text on a PSP is caused by the browser attempting to format a website to fit onto the smaller screen. This is used to prevent the need to scroll back and forth across the screen.
Format Solution
Change the formatting on the browser by selecting "View," then "Display Mode" and then choose "Normal" to make the formatting the same as a standard website.
Text Size Solution
To keep the formatting adjusted so you do not need to scroll, select "View" then "Text Size" and select "Small." This will decrease the text size to prevent overlapping and jumbled words.
