issue with locale text transform

[szolowicz]

Case transforming is returning wrong output, because text transform methods take user localization into account.

For example in Turkish (before & after):

"Unlike toLowerCase, toLocaleLowerCase takes localization into account. In most cases, with most languages, they will produce similar output, however certain languages will behave differently."

Fix: locale -> normal
