This option is deprecated on Qt since 5.12. Konsole cmake minimal Qt
version set is 5.12, giving warning messages while making.
A regular expression is automatically optimized the first time it is
used now.
This reverts commit f96deb39aa.
This was anti-optimization.
QStringLiteral is a QString created at build time. Initialization of
QString with it has no overhead.
QLatin1String is 8 bit C string wrapper which needs run-time conversion
to 16 bit encoding used in QString.
Summary:
Since minimum Qt version is 5.9.7, code for older versions is not
needed.

Summary:
The uni2characterwidth tool, converts Unicode Character Database files
into character width lookup tables. It uses a template file to place
the tables in a source code file together with a function for finding
the width for specified character. It also allows to generate few forms
of lists with width data for debug and test purposes, or for future use
as a replacement of Unicode files.
Set `KONSOLE_BUILD_UNI2CHARACTERWIDTH` cmake flag to build the tool.
Use `--help` argument for more detailed usage.
There is a possibility to generate separate "width" for Ambiguous
characters. It can be used to add ability to configure the characters
width in Konsole settings.
The `example.template` file contains all possible named tags, and some
additional tags to show how to use them.
CCBUG: 396435
Depends on D15756
Test Plan:
Download files listed below from `11.0.0` and `emoji/11.0` directories
on `https://unicode.org/Public/`. You can also directly use URLs to the
files.
* UnicodeData.txt
* EastAsianWidth.txt
* emoji-data.txt
Generate any available list except compact-ranges (e.g. `details`):
```
uni2characterwidth \
-U UnicodeData.txt -A EastAsianWidth.txt -E emoji-data.txt \
-g details result.txt
```
The list should contain ranges for all possible widths
(-2, -1, 0, 1, 2). You can choose some characters with a width you know
and check how they were classified. -2 is a special non-standard width
for ambiguous characters, which can be overriden by adding `-a 1` or
`-a 2` parameter. With this flag, all ranges from -2 group should
disappear and become assigned to selected width (1 or 2).
Generate output using a template:
```
uni2characterwidth \
-U UnicodeData.txt -A EastAsianWidth.txt -E emoji-data.txt \
-g code,./template.example result.txt
```
